Thanks, I suspected that that would be a reasonable plan, and I've just
checked that this doesn't seem to require upgrades to user space.

Now one thing about my system is that mounting /usr will be a bit
awkward, since it is lvm over several raid 5 devices.  Can anyone think
of a way to install a kernel .deb without having /usr mounted?  If I
just unpack it with dpkg-deb, copy the kernel, initrd and modules dir
to the right place, and update grub, will that be enough??

Thanks,

Dan
