I have done it many times from LiveCD, also from Single user mode. I had
to turn off some logging and other things even in single user mode.

Effectively you have to make sure you get everything. If you are running
Ubuntu there are additional items you need to make sure are taken care
of. (Make sure /var/run and /var/lock are on the root partition for
tmpfs filesystems)

But like I said, I have done it multiple times... heck even once
accidentally reformatted the /var filesystem AND deleted all backups
before the retore, having to recreate it from scratch on the new

So, what did you do to move it? (list of commands used, would be good)
