Mount one file to another (with offset and append_only support)
Examples:
Simplest mode
echo qqq > source touch mountpoint fusefile source mountpoint
1KB random file (frandom is a fast urandom)
fusefile /dev/frandom mountpoint -r -S 1024 -M 0100666
Instead of "losetup -r -o"
fusefile /dev/sda sda1_readonly -r -S 1024 -O $((63512)) -S $((626535512)) -M 0100600
Append-only public log using FUSE
fusefile /var/log/mylog publiclog -a -M 0100777 -o allow_other
Force a file to be "regular"
fusefile /dev/uba1 mountpoint -w -M 0100600 -S blockdev --getsize64 /dev/uba1
