I used rsync. And had the wrong combination of slashes in the command
so it copied the old /boot to the new /boot/boot. As a result, it
found no kernel to boot.

Fixing that, and realy going over the old and new etc/fstab I now have
a situation where at boot time I have the choice of a Devunn system and
an unidentified Liux system. Both in plin and advanced flavours.

However, when booting the unidentified Linux system, it mounts exactly
the same partitions as the old Linux system. It appears to
completely ignore the new /etc/fstab in the new system.

It's as if grub-update found the new system, but for perverse reasons
still used the /etc/fstab in the old system instead of the one in the
new system. And yes, I exclude /etc/fstab from the rsyc operation.
The new one is definitely still different from the old one.

Next I'll check whether /boot/grub/grub.cfg refers to the proper
partitions. That should narrow down the possibilities.
