I use the UUIDs, I find they're easy enough to find out, but I avoid
grub 2 like the plague; the three machines I have Ubuntu installs on
and I use on a regular basis all use extlinux instead. I have to
manually update the configuration file when the kernel is updated, but
that's not a big deal. By comparison, extlinux is dead easy to
understand and modify. None of these machines multiboot though so I
guess my use case is pretty simplistic.
