My fault, I missed some context. The Debian version of GRUB includes one of
those patches that added support for --once by embedding a once_only bit in
stage files. Based on this, I wrote a "grub-reboot" script that mimics
"lilo -R" functionality.

Since setting up GRUB to boot a particular option once, then fallback to
default requires editing menu.lst, grub-reboot can't now be implemented
gracefuly.

I think some sort of interface like that in /boot/grub/default would be
quite adequate. It could also allow for testing a list of kernels untill
default is reached.
