finit - Finit v4.1

Published by troglobit over 3 years ago

Bug fix release. Also disables handlers for SIGINT and SIGPWR, a new set of sys conditions are instead generated which can be used to trigger external programs.

Changes

  • Change behavior on SIGUSR1 to be compatible with sysvinit and systemd. Previously SIGUSR1 caused Finit to halt, like BusyBox init. This had "interesting" side effects on Debian systems when coexisting with sysvinit (upgrading/reinstalling causes scripts to kill -USR1 1)
  • Change how contrib/debian/install.sh sets up a Grub boot entry for finit. We now modify the $SUPPORTED_INITS variable in 10_linux
  • Disable default kernel ctrl-alt-delete handler and let Finit instead catch SIGINT from kernel to be able to perform a proper reboot. There is no default command for this, you need to set up a task that triggers on <sys/key/ctrlaltdel> to issue initctl reboot
  • Added keventd to provide <sys/pwr/ac> condition to Finit. keventd is currently only responsible for monitoring /sys/class/power_supply for changes to active AC mains power online status. Enable keventd with configure --with-keventd
  • For handling power fail events (from UPS and similar) a process may send SIGPWR to PID 1. Finit no longer redirects this to SIGUSR1 (poweroff). There is no default command for this, you need to set up a task that triggers on <sys/pwr/fail> to issue initctl poweroff
  • Built-in Finit getty is now a standalone program
  • Default termios for TTYs now enable IUTF8 on input
  • If /bin/login is not found, Finit now tries sulogin before it falls back to an unauthenticated /bin/sh
  • Dropped (broken) support for multiple consoles. Finit now follows the default console selected by the kernel, /dev/console
  • Dropped signal handlers for SIGSTOP/TSTP and SIGCONT
  • Added support for \n, in addition to \r, in "Please press Enter" prompt before starting getty
  • Finit no longer parses /proc/cmdline for its options. Instead all options are by default now read from argv[], like a normal program, this is also what the kernel does by default. Please note, this may not work if your systems boots with an initramfs (ymmv), for such cases, see configure --enable-kernel-cmdline
  • The following plugins are now possible to disable (for containers): rtc.so, urandom.so, you may also want to disable hotplug.so. They are all enabled by default, as in Finit 4.0, but may be moved to external tools or entries in finit.conf in Finit 5.0
  • Added support for reading PRETTY_NAME from /etc/os-release to use as heading in progress output, unless --with-heading=GREET is used.
  • Added manual pages for finit(8), initctl(8), and finit.conf(5)

Fixes

  • Stricter interface name validation in netlink plugin, modeled after the kernel. Suggested by Coverity Scan

  • Fix problem of re-registering a service as a task. Previously, if a fundamental change, like type, was made to an active service/run/task it did not take. Only possible workaround was to remove from config

  • initctl: drop warning when removing a non-existing usr condition

  • initctl: drop confusing errno 0 when timing out waiting for reply

  • Ensure services in plugins and from Finit main belong to a cgroup

  • Ensure init top-level cgroup remains a leaf group

  • Fix tty parse error for detecting use of external getty

  • Fix default name: and :ID for tty's, e.g. ttyS0 now gives tty:S0 as expected. This was default for built-in getty already

  • Fix max username (32 chars) in bundled Finit getty

  • The contrib/*/install.sh scripts failed to run from tarball

  • Finit no longer forcibly mounts; /dev, /proc, or /sys, instead it checks first if they are already mounted (devtmpfs or container)

  • Fix /etc/fstab parser to properly check for 'ro' to not remount the root filesystem at boot. The wrong field was read, so a root mounted by an initramfs, or by lxc for a container, had their root remounted

  • Fix SIGCHLD handler, waitpd() may be interrupted by a signal

  • Reset starting flag of services being stopped. When a service is started and then stopped before it has created its pid file, it could be left forever in the stopping state, unless we reset the starting flag.

  • Fix #170: detect loss of default route when interfaces go down. This emulates the missing kernel netlink message to remove the condition net/default/route to allow stopping dependent services

  • Fix #171: restore automatic mount of /dev/shm, /dev/pts, /run and /tmp, unless mounted already by /etc/fstab. This is what most desktop systems expect PID 1 to do. Here we also make sure to mount /run/lock as a tmpfs as well, with write perms for regular users, this prevents regular users from filling up /run and causing DoS.

  • Fix #173: netlink plugin runs out of socket buffer space;

      finit[1]: nl_callback():recv(): No buffer space available

    Fixed by adding support for resync with kernel on ENOBUFS. See netlink(7) for details. As a spin-off the plugin now supports any number of interfaces and routes on a system. On resync, the following message is now logged, as a warning:

      finit[1]: nl_callback():busy system, resynchronizing with kernel.

  • Fix #174: loss of log messages using combo of prio and facility, e.g., logit(LOG_CONSOLE | LOG_NOTICE, ...), by Jacques de Laval, Westermo

  • Fix #175: ensure Finit does not acquire a controlling TTY when checking if a device is a TTY before starting a getty. This fixes an old bug where Ctrl-C after logout from a shell could cause PID 1 to get SIGINT, which in turn could lead to a system reboot

finit - Finit v4.0

Published by troglobit over 3 years ago

This release became v4.0, and not v3.2, because of incompatible changes to service conditions. There are other significant changes as well, so make sure to read the whole change log when upgrading.

Changes

  • The stand-alone reboot tool has been replaced with a symlink to initctl, like its siblings: halt, shutdown, poweroff, and suspend. Calling reboot & C:o now defaults to the corresponding initctl cmd with a fallback to sending signals as per traditional SysV init. The -f (force) flag remains, where reboot(2) is called directly
  • Introducing Finit progress 𝓜𝓸𝓭𝓮𝓻𝓷
  • The inictl cond set|clear COND have changed completely. Constrained to a flat <usr/...> namespace and automatically activated by a new usr.so plugin that checks services for usr condition changes
  • Removed built-in inetd super server. If you need this functionality, use an external inetd, like xinetd, instead. A pull request for a stand-alone inetd, like watchdogd and getty, is most welcome!
  • Incompatible configure script changes, i.e., no guessing --prefix and other paths. Also, many options have been changed, renamed, or flipped defaults, or even dropped altogether. There are examples in the documentation and the contrib/ section
  • Service conditions change from the non-obvious <svc/path/to/foo> to <pid/foo:id>. Not only does this give simpler internal semantics, it hopefully also makes it clear that one service's pid:!foo pidfile is another service's <pid/foo> condition, issue #143
  • Initial support for cgroups v2:
    • services runs in a cgroup named after their respective *.conf file
    • top-level groups are; init, user, and system
    • all top-level groups can be configured from finit *.conf files
    • each service can tweak the cgroup settings
    • Use initctl [top|ps|cgroup] commands to inspect runtime state
    • https://twitter.com/b0rk/status/1214341831049252870?s=20
  • Major refactor of Finit's main() function to be able to start the event loop earlier. This also facilitated factoring out functionality previously hard-coded in Finit, e.g., starting the bundled watchdogd, various distro packed udevd and other hotplugging tools
  • A proper rescue mode has been added. It is started extremely early and is protected with a bundled suslogin. Exiting rescue mode now brings up the system as a normal boot, as one expects
  • Support for sysv start/stop scripts as well as monitoring forking services, stared using sysv or service stanza
  • Support for custom kill:DELAY, default 3 sec.
  • Support for custom halt:SIGNAL, default SIGTERM
  • Support for pre:script and post:script, allows for setup and teardown/cleanup before and after a service runs, issue #129
  • Support for env:file in /etc/default/foo or /etc/conf.d/foo, see the contrib section for examples that utilize this feature. Variables expanded from env files, and the env files themselves, are tracked for changes to see if a service .conf file is "dirty" and needs restart on initctl reload
  • Support for tracking custom PID files, using pid:!/path/to/foo.pid, useful with new sysv or service which fork to background
  • Support starting run/task/services without absolute path, trust $PATH
  • Add support for --disable-doc and --disable-contrib to speed up builds and work around issue with massively parallel builds
  • Support for @console also for external getty
  • Support for notty option to built-in getty, for board bring-up
  • Support for rescue option to built-in getty, for rescue shells
  • Add -b, batch mode, for non-interactive use to initctl
  • Prefer udev to handle /dev/ if mdev is also available
  • Redirect dbus daemon output to syslog
  • Set $SHELL, like $PATH, to a sane default value, needed by BusyBox
  • Finit no longer automatically reloads its *.conf files after running /etc/rc.local or run-parts. Use initctl reload instead.
  • initctl without an argument or option now defaults to list services
  • Convert built-in watchdog daemon to standalone mini watchdogd, issue #102
  • Improved watchdog hand-over, now based on svc_t and not PID
  • Extended bootstrap, runlevel S, timeout: 10 --> 120 sec. before services not allowed in the runtime runlevel are unconditionally stopped
  • Removed HOOK_SVC_START and HOOK_SVC_LOST, caused more problems than they were worth. Users are encouraged to use accounting instead
  • Skip displaying "Restarting ..." progress for bootstrap processes
  • Added a simple work queue mechanism to queue up work at boot + runtime
    • Postpone deletion of svc_t until any SIGKILL timer has elapsed
    • As long as a stepped service changes state we queue another step all event, because services may depend on each other
  • Require new libuEv API: uev_init1() to reduce event cache so that the kernel can invalidate deleted events before enqueing to userspace
  • Rename hwclock.so plugin to rtc.so since it now is stand-alone from the hwclock tool. Note: the kernel can also be set to load and store RTC to/from system clock at boot/halt as well, issue #110
  • New plugin to support cold plugging devices, auto-loading of modules at boot. Detects required modules by reading /sys/devices/*
  • New plugin for /etc/modules-load.d/ by Robert Andersson, Atlas Copco
  • New name:foo support for services, by Robert Andersson, Atlas Copco
  • New manual:yes support for services, by Robert Andersson, Atlas Copco
  • New log:console support for services, by Robert Andersson, Atlas Copco
  • Support for :ID as a string, by Jonas Johansson, Westermo
  • Support for auto-reload, instead of having to do initctl reload, when a service configuration has changed. Disabled by default, but can be enabled with ./configure --enable-auto-reload
  • Support for logging security related events, e.g., runlevel change, start/stop or failure to start services, by Jonas Holmberg, Westermo
  • Mount devtpts with recommended ptxmode=0666
  • Mount /run tmpfs with nosuid,nodev,noexec for added security
  • Support for console as alias for @console in tty stanzas
  • Drop --enable-rw-roots configure option, use rw for your / partition in /etc/fstab instead to trigger remount at boot
  • Drop default tty speed (38400) and use 0 (kernel default) instead
  • Make :ID optional, use NULL/zero internally this allows ...
  • Handle use-cases where multiple services share the same PID file and thus the same condition path, e.g. different instances for different runlevels. Allow custom condition path with name:foo syntax, creates conditions w/o a path, and ...
  • Always append :ID qualifier to conditions if set for a service
  • The IPC socket has moved from /run/finit.sock to /run/finit/socket officially only supported for use by the initctl tool
  • The IPC socket now uses SOCK_SEQPACKET instead of SOCK_STREAM.
    Recommend using watchdogd v3.4, or later, which support this
  • Improved support for modern /etc/network/interfaces, which has include statements. No more native ifup of individual interfaces,
    Finit now calls ifup -a, or ifdown -a, delegating all details to the operating system. Also, this is now done in the background, by popular request

Fixes

  • Fix #96: Start udevd as a proper service
  • Ensure we track run commands as well as task/service, once per runlevel
  • Ensure run/tasks also go to stopping state on exit, like services, otherwise it is unnecessarily hard to restart them
  • Fix missing OS/Finit title bug, adds leading newline before banner
  • Remove "Failed connecting to watchdog ..." error message on systems that do not have a watchdog
  • Fix #100: Early condition handling may not work if /var/run does not yet exist (symlink to /run). Added compat layer for access
  • Fix #101: Built-in inetd removed
  • Fix #102: Start built-in watchdogd as a regular service
  • Fix #103: Register multiple getty if @console resolves to >1 TTY,
  • Fix #105: Only remove /etc/nologin when moving from runlevel 0, 1, 6. Fixed by Jonas Johansson, Westermo
  • Fix #109: Support for PID files in sub-directories to /var/run
  • Handle rename of PID files, by Robert Andersson, Atlas Copco
  • Fix #110: automatic modprobe of RTC devices, built-in hwclock
  • Fix #120: Redirect stdin to /dev/null for services by default
  • Fix #122: Switch to nanosleep() to achieve "signal safe" sleep. Fixed by Jacques de Laval, Westermo
  • Fix #124: Lingering processes in process group when session leader exits. E.g., lingering logit processes when parent dies
  • Fix #127: Show all runparts scripts as they start, like rc.local. Fixed by Jacques de Laval, Westermo
  • Fix service name matching, e.g. for condition handling, may match with wrong service. Fixed by Jonas Holmberg, Westermo
  • Run all run-parts scripts using /bin/sh -c foo just like the standard run-parts tool. Found by Magnus Malm, Westermo
  • Fix initctl [start | restart], should behave the same for services that have crashed. Found by Mattias Walström, Westermo
  • Wait for bootstrap phase to complete before cleaning out any bootstrap processes that have stopped, they may be restarted again
  • Reassert condition when an unmodified run/task/service goes from WAITING back to RUNNING again after a reconfiguration event. Found and fixed by Jonas Johansson, Westermo
  • Restore Ctrl-D and Ctrl-U support in built-in getty
  • Remove service condition when service is deleted
  • Fix C++ compilation issues, by Robert Andersson, Atlas Copco
  • Build fixes for uClibc
  • Provide service description for built-in watchdog daemon
  • Fix #138: Handle SIGPWR like SIGSUR2, i.e., power off the system
  • Drop the '%m' GNUism, for compat with older musl libc
  • Fix #139: call tzset() on initctl reload to activate system timezone changes (for logging)
finit - Finit v4.0-rc4

Published by troglobit over 3 years ago

This is a pre-release, for internal testing at Westermo at the moment. Version 4.0 replaces the previously planned 3.2 because of major changes, for instance; removal of the built-in inetd, incompatible changes to kernel command options and configure script. See the changelog for more detailed information. A fully up-to-date list of changes is expected for the GA release.

  • Added a simple work queue mechanism to queue up work at boot + runtime
    • Postpone deletion of svc_t until any SIGKILL timer has elapsed
    • As long as a stepped service changes state we queue another step all event, because services may depend on each other
  • Require new libuEv API: uev_init1() to reduce event cache so that the kernel can invalidate deleted events before enqueing to userspace

Fixes

  • Fix #96: Start udevd as a proper service
  • Ensure we track run commands as well as task/service, once per runlevel
  • Fix #98: FTBFS with --disable-inetd
  • Make sure to unblock UDP inetd services when connection terminates. Regression introduced in v3.1
  • Ensure run/tasks also go to stopping state on exit, like services, otherwise it is unnecessarily hard to restart them
  • Fix #99: Do not try to SIGKILL inetd services, they are not backed by a PID. This caused a use after free issue crashing finit. Found and fixed by Tobias Waldekranz, @wkz, Westermo
  • Fix missing OS/Finit title bug, adds leading newline before banner
  • Remove "Failed connecting to watchdog ..." error message on systems that do not have a watchdog
  • Fix #100: Early condition handling may not work if /var/run does not yet exist (symlink to /run). Added compat layer for access
  • Fix #103: Register multiple getty if @console resolves to >1 TTY
  • Fix #105: Only remove /etc/nologin when moving from runlevel 0, 1, 6
  • Fix #106: Don't mark inetd connections for deletion at .conf reload. Fixed by Jonas Johansson, @jonasj76, Westermo
  • Fix #107: Stop spawned inetd conncections when stopping inetd service. Fixed by Jonas Johansson, @jonasj76, Westermo
  • Fix #111: Only restart inetd services when necessary. E.g., if the listening interface is changed. Only stop established connections which are no longer allowed, i.e. do not touch already allowed established connections. Fixed by Jonas Johansson, @jonasj76, Westermo
  • Fix: update inetd service args on config change. Found and fixed by Petrus Hellgren, @ptruz, Westermo
  • Fix initctl [start | restart], should behave the same for services that have crashed. Found by Mattias Walström, @mattiaswal, Westermo
  • Wait for bootstrap phase to complete before cleaning out any bootstrap processes that have stopped, they may be restarted again
  • Reassert condition when an unmodified run/task/service goes from WAITING back to RUNNING again after a reconfiguration event. Found and fixed by Jonas Johansson, @jonasj76, Westermo
  • Remove service condition when service is deleted
finit - Finit v3.1

Published by troglobit over 6 years ago

Improvements to netlink.so plugin, per-service rlimit support, improved integration with watchdogd, auto-detect TTY console. Much improved debug, rescue and logging support. Also, many fixes to both big and small issues, most notably in the condition handling, which no longer is sensitive to time skips.

This version requires at least libuEv v2.1.0 and libite v2.0.1

Changes

  • Support for more kernel command line settings:
    • splash, enable boot progress
    • debug, like --debug but also enable kernel debug
    • single, single user mode (no network)
    • rescue, new rescue mode
  • Support for IFF_RUNNING to netlink plugin => net/IFNAME/running
  • Support for restarting initctl API socket on SIGHUP
  • Greatly updated initctl status <JOB|NAME> command
  • Support for rlimit per service/run/task/inetd/tty, issue #45
  • Support for setting hard and soft rlimit for a resource at once
  • Support for auto-detecting serial console using Linux SysFS, the new tty @console eliminates the need to keep track of different console devices across embedded platforms: /dev/ttyS0, /dev/ttyAMA0, etc.
  • Add TTY nologin option. Bypasses login and skips immediately to a root shell. Useful during board bringup, in developer builds, etc.
  • Support for calling run/tasks on Finit internal HOOK points, issue #18
  • Removed support for long-since deprecated console DEV setting
  • Cosmetic change to login, pressing enter at the Press enter to ... prompt will now replace that line with the login issue text
  • Calling initctl without any arguments or options now defaults to show status of all enabled services, and run/task/inetd jobs
  • Cosmetic change to boot messages, removed Loading plugins ..., start of inetd services, and Loading configuration .... No end user knows what those plugins and configurations are, i.e. internal state+config
  • Change kernel WDT timeout (3 --> 30 sec) for built-in watchdog daemon
  • Advise watchdog dawmon on shutdown and reboot using SIGPWR and then SIGTERM. It is recommended the daemon start a timer on the first signal, in case the shutdown process somehow hangs.
  • Handle /etc/ OverlayFS, reload /etc/finit.d/*.conf after mount -a
  • initctl: Add support for printing previous runlevel
  • initctl: Support short forms of all commands
  • initctl: Support for initctl touch <CONF> to be used with reload
  • initctl: Improved output of initctl show <SVC>
  • Support reloading /etc/finit.conf. The main finit.conf file previously did not support reloading at runtime, as of v3.1 all configuration directives supported in /etc/finit.d/*.conf are now supported in /etc/finit.conf
  • Change .conf dependency + reload handling. Finit no longer relies on mtime of .conf files, instead an inotify handler tracks file changes for time insensitive dependency tracking
  • Change condition handling to not rely on mtime but a generation id.
  • New configure script option --enable-redirect to automatically redirect stdout and stderr of all applications to /dev/null
  • New pid sub-option to services when a service does not create a PID file, or when the PID file has another name. Issue #95
  • Greatly improved log sub-option to service/run/tasks, selectively redirect stdout and stderr using the new tool logit to either syslog or a logfile. Issue #44
  • Support for automatic log rotation of logfiles created by log option. Use configure --disable-logrotate on systems with a dedicated log rotation service. Issue #44
  • Support for disabling service/run/task progress with empty -- description. Note: no description separator gives a default desc.
  • Create /etc/mtab symlink if missing on system (bootmisc plugin)
  • New hook: hook/mount/post runs after mount -a but before the hook/mount/all, where bootmisc.so runs. This provides the possibility of running a second stage mount command before files in /run and similar are created
  • Skip gdbserver when unleashing the grim reaper at shutdown
  • Distribute and install docs/ and contrib/ directories

Fixes

  • Reset TTY before restarting it. A program may manipulate the TTY in various ways before the user logs out, Finit needs to reset the TTY to a sane state before restarting it. Issue #84
  • On .conf parse errors, do not default to set TTY speed 38400, reuse current TTY speed instead
  • Fix run/tasks, must be guaranteed to run once per declared runlevel. All run/tasks on [S] with a condition <...> failed to run. Finit now tracks run/tasks more carefully, waiting for them to finish before switching to the configured runlevel at boot. Issue #86
  • Allow inetd services to be registered with a unique ID, e.g. :161, issue #87. Found by Westermo
  • inetd: drop UDP packets from blocked interfaces, issue #88
  • Handle obscure inter-plugin dependency issue by calling the netlink plugin before the pidfile plugin on HOOK_SVC_RECONF events
  • Handle event loop failure modes, issue found by Westermo
  • Handle API socket errors more gracefully, restart socket
  • Do not attempt to load kernel modules more than once at bootstrap
  • Remove reboot symlinks properly on uninstall
  • Fix regression in condition handling, reconf condition must be kept as a reference point to previous reconfiguration, or bootstrap.
  • Fix nasty race condition with internal service stop, abort kill if the service has already terminated, otherwise we may do kill(0, SIGKILL)
  • Fix reconfiguration issue with (very quick) systems that don't have highres timers
  • Fix formatting of runlevel string in initctl show
  • Allow running initctl with STDOUT redirected
  • Fix regression in initctl start/stop <ID>, using name worked not id
  • Fix error handling in initctl start/stop without any argument
  • Fix issue #81 properly, remove use of SYSV shm IPC completely. Finit now use the API socket for all communication between PID 1 and initctl
  • Fix segfault on x86_64 when started with kernel cmdline --debug
  • Normalize condition paths on systems with /run instead of /var/run

finit - Finit v3.0

Published by troglobit about 7 years ago

Major release, support for conditions/dependencies between services, optional built-in watchdog daemon, optional built-in getty, optional built-in standard inetd services like echo server, rdate, etc.

Also, native support for Debian/BusyBox /etc/network/interfaces, overhauled new configure based build system, logging to /dev/kmsg before syslogd has started, massively improved support for Linux distributions.

Changes

  • Added basic code of conduct covenant to project

  • Added contribution guidelines document

  • Removed finit.conf option check DEV, replaced entirely by automated call to fsck for each device listed in /etc/fstab

  • Add support for initctl log <SVC>, shows last 10 lines from syslog

  • Add initctl cond dump for debugging conditions

  • Ensure plugins always have a default name, file name

  • Reorganization, move all source files to a src/ sub-directory

  • Add support for initctl <list|enable|disable> <SVC>, much needed by distributions. See doc/distro.md for details

  • New table headings in initctl, using top style inverted text

  • Allow initctl show to use full screen width for service descriptions

  • New HOOK_BANNER for plugins to override the default banner()

  • Allow loading TTYs from /etc/finit.d

  • Allow using both built-in getty and external getty:

      tty [12345] /dev/ttyAMA0    115200              noclear vt220
  tty [12345] /sbin/getty  -L 115200 /dev/ttyAMA0 vt100
  tty [12345] /sbin/agetty -L ttyAMA0 115200      vt100 nowait

  • Silent boot is now the default, use --enable-progress to get the old
    Finit style process progress. I.e., --enable-silent is no more

finit - Finit v2.4

Published by troglobit almost 9 years ago

Bug fix release.

Changes

  • Add support for status/show service by name:id
  • Enforce terse mode after boot, if verbose mode is disabled
  • Reenable verbose mode at reboot, if disabled at boot
  • Update section mentioning BusyBox getty
  • Update debugging documentation
  • Allow debug to override terse mode
  • Revert confusing change in service state introduced in v2.3.
    As of v2.4 services are listed as "halted" and "stopped", when
    they have been halted due to a runlevel changed or stopped by
    the user, respectively.

Fixes

  • Fix system freeze at reconfiguration. Changed services that
    all support SIGHUP caused a freeze due to Finit waiting for
    them to stop.
  • Make sure to start and/or SIGHUP services after reconfiguration
    when there was no services to stop.
finit - Finit v2.3

Published by troglobit almost 9 years ago

Bug fix release.

Changes

  • Add support for stop/start/restart/reload service by name:id
  • Refactor service status listed in initctl show, show actual status

Fixes

  • Remove bootstrap-only tasks/services when leaving runlevel 'S'
  • Fix reference counting issue with already stopped and removed services
    when the user performs initctl reload to change system configuration
  • Revert semantic change in behavior of initctl restart: users expect
    service to be stopped/started, not reloaded with SIGHUP even if the
    service supports it
  • Fix NULL pointer dereference causing kernel panic when user calls
    initctl reload after change of system configuration
  • Fix column alignment in output of initctl show for services not in
    current runlevel
finit - Finit v2.2

Published by troglobit almost 9 years ago

Lots of fixes to handle static builds, but also fixes for dynamic event
handling and reconfiguration at runtime.

Changes

  • Upgrade to libuEv v1.2.4, to handle static builds

  • Clarify how to select different plugins with the configure script
  • Improve urandom plugin for embedded systems w/o random seed
  • Add --debug flag to initctl
  • The runlevels listed for services in initctl show now hightlight the
    active runlevel.
  • Clarify in the README and in initctl help that the GW event to
    listen for in service declarations is GW:UP

Fixes

  • Build fixes for configure --disable-inetd
  • Fixed issue #14: Improved support for static Finit builds
  • Misc. fixes to silence warnings when building a static Finit
  • Default to register services as SIGHUP'able, regression in v2.0
  • Call HOOK_SVC_RECONF only when all processes have been stopped
  • On reload/reconf we must wait for all services to stop first
  • Only trigger on events that matches the service's specification,
