Yes, but we don't change kernel versions that often and it's easy to
fix this from grub's boot prompt should the old kernel no longer boot.

you can find the last vmlinuz-2.6.*-xen0 installed with a command like
this:
ls -t dist/install/boot/vmlinuz-2.6.*-xen0 | head -1

How about adding this to install.sh:
(run in dist/install/boot)
(echo '2.6.*' -2.6; echo '2.4.*' -2.4) | while read m v
do
  l=$(eval ls -t vmlinuz-$m-xen0 2>/dev/null | head -1)
  [ -e "$l" ] && ln -fs "$l" vmlinuz${v}-xen0
done

You can even add another echo '2.*.*' '' if you want to get a link
vmlinuz-xen0 pointing to the last xen0 (2.4 or 2.6) installed, but
I think that's not a good idea because it can have very unexpected
behaviour.
