Is there an easy method to restart a FAI Installation without rebooting the target machine?
Usually, when an installation is finished, "<enter to reboot>" appears.
In our FAI environment, the user/admin can choose some parameters during the FAI installation process (in the "defclass.DEFAULT" hook) e.g what kind of operating system should be installed on the target machine. This settings can also be done remote over SSH.
This picture summarizes our installation procedure:

Sometimes it happens that the admin chooses wrong settings and needs to reinstall the machine. Normaly we tell our users "Could you please reboot the machine again with our USB stick?" and we can redefine our settings and restart the installation process over ssh. But sometimes no user is available who could do that job (or we simply don't want to bother our users)

I tried it with these commands and it works but it doesn't look nice

umount /var/lib/fai/config/
umount /target/dev/pts
umount /target/boot/
umount /target/sys/
umount /target/proc/
umount /target/dev
umount /target/
/etc/init.d/rcS

Is there an easier solution availabe? e.g "fai-restart-installation" ?
