implement rescue mode installation via -r
if you have an alix board and like to have a fallback safemode system, you can use adkinstall with -r and install a kernel with initramfs as a read-only never changing rescue image. Grub will then installed on the same rescue partition on the compact flash card, to avoid a broken system after grub upgrade. System should always come up with the rescue system without any dependency to the live system.
