I am trying to remotely debug a linux kernel problem which causes the
machine to reboot early in the bootup process. When this happens, the
machine goes into an infinite loop attempting to boot.
It would be nice to be be able to override the default menu entry that
grub boots into, but only for a specified number of boots (or
unsuccessful boots). This could be hardcoded at "1".
(Like a poor-man's "last known good" bootup capability )
This would allow safer updates to the boot-loader configurations of
remote machines, since by setting the count to "1", one could make a
change and have some chance that if the boot is not successful, the next
boot will revert to the prior "known good" config. Differentiation
between successful and unsuccessful boots, which is really an "extra
credit" feature, could be signaled by a monotonically incrementing count
stored within a file in the boot partition.
Or, someone could point me to an existing solution...
Thanks!
Andrew
