I have multiple (would you believe 2?) kernels in /boot.
[x8940][waltdnes][~] ll /boot/vm*
-rwxr-xr-x 1 root root 7046848 Jun 12 23:46 /boot/vmlinuz-experimental
-rwxr-xr-x 1 root root 6986624 Jun 12 16:55 /boot/vmlinuz-production
The grub kernel listing at bootup is
- production kernel
- production kernel recovery mode
- experimental kernel
- experimental kernel recovery mode
The default is the first entry, i.e. "GRUB_DEFAULT=0" in
/etc/default/grub. I prefer going with "experimental". If I screw up
the config to the point where it can't boot, then I'll manually override
to "production". The simple way of getting the third entry as default
is "GRUB_DEFAULT=2" (remember to count from zero).
This works for now. But what happens if/when I add more kernels for
whatever reason? Let me rephrase the question more generally... given a
kernel "/boot/vmlinuz-fubar" how and where do I specify it by name as
the default boot kernel?
