at mount of root might not be bad...

that would do.. or maybe we could ask a second question about setting
output-device if the machine is in the list of `we think it will work'

otherwise a specific kernel version is written into /etc/yaboot.conf,
if we point yaboot at a symlink the user only has to repoint the
symlink on kernel upgrades, no need to edit /etc/yaboot.conf and rerun
ybin.  kernel-image .debs will do that automatically (an in /boot
rather then / if so configured in /etc/kernel-img.conf).

yaboot won't have a problem with a relative symlink so long as it
works within /boot alone (if its a partition).  so a symlink foo ->
bar will work with yaboot, but a symlink foo -> /boot/bar will not
since /boot is / as far as yaboot cares.

i think i am going to delete the /vmlinux symlink if /boot is a
partition, it will only annoy yabootconfig and cause confusion i
think.

i saw the quik dialog changes, but nothing in that symlink stuff..
