Public bug reported:
I was running a tweaked command line version of 2.6.35-12 to get over bugs in
nouveau as a new grub entry.
This required me to set GRUB_DEFAULT=6 in my /etc/defaultgrub
On upgrade to 2.6.35-14 as part of Maverick updates the new kernel was
"inserted" and results (either by update-grub or by grub-pc itself
during boot) with the entries (normal and recovery versions) being the
first in the list. GRUB_DEFAULT should have been set to 8 to compensate
for the new entries but it remained at 6 resulting in the system booting
the wrong image upon restart. (It booted memtest86 as it happens!).
Obviously the workaround to get the system working is to interrupt grub
with shift key, select the right kernel and once booted manually update
the default to the required entry (in my case editing the entry to
point to the new kernel).
It is not reasonable to cope with all possible manual alterations to
grub settings but this one should have been dealt with automatically as
it is 100% deterministic and the consequence of the kernel upgrade
scriplet.
