[gentoo-user] Exact setting in grub to default to a kernel by name?

["Walter Dnes" <waltdnes@waltdnes.org>]

  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?
