Tip

The custom folder is a mirror of squashfs-root. All file in custom will be copied and replace to squashfs-root folder when exit from chroot environment

The custom.sh file will run outside of chroot when exit chroot environment, this a special script if you want do some housekeeping (remove unused file, inject new line, etc...)

To add custom run script, please use init.d/rc35 file
