Arch Linux install helper for thinkpad t460p

This is only meant to provide a simple, basic and self-usage install helper for thinkpad t460p only. It will ultimately give user a console as a start point. For a full installation process I have went through, please check my blog

Precondition

Following conditions need to meet:

EFI boot mode is enabled from firmware (press F1 during boot)
Network is reachable via either ethernet or wireless

Usage

Two scripts are provided during different phases: install phase and configuration phase

For installation phase, you will be booted via a live system from usb media for example. Then you will need to download these two scripts from web or via another usb media(e.g. I put it in a movable disk and I have to install ntfs-3g first and then mount the disk via mount -t ntfs-3g ... ).

Afterwards, you can just run 1st script: install.sh. This script perform following actions:

verify boot mode
connect network
update system clock
identify the disk device
(opt)create and format partitions
mount file system
select live system mirrors
install the base, wireless and microcode packages
fstab
chroot

They are ordered by the arch wiki

At the end of this script, it will run arch-chroot, which will immediately stop the process and bring you to the changed rootfs. This is why we have 2 scripts. Just before arch-chroot, we have copied the 2nd script, i.e. config.sh to the newly created fs. Therefore, after exit from install.sh, just run config.sh.

In the config.sh, we perform following actions:
