I don't think menu.lst exists anymore (I just double-checked on my
desktop computer) in grub2.  Do you mean some components thought you
were using grub and others thought you were using grub2?

I had another crazy thought this morning.  If I boot from livecd, then
put the same "mount --bind and chroot" trick from that web page,  then
apt-get update && apt-get upgrade (or dist-upgrade), would that actually
update the packages on my installed kubuntu?  It's so crazy it just may
work. I'm almost guaranteed of there being a newer kernel available,
since I don't update my servers that often.

What would be *really* nice is if I could launch muon from that chrooted
shell and update using it, but I'm less confident that it would respect
the chroot.  Idunno.
