I've done this several times, to install xfs support on live machines
(ie. on my desktop and laptop that were already full of crap junk and
other kind of files).

rsync -av --exclude /proc --exclude /home/ / /newroot/

Exclude every mount point from the rsync and do this for every
partition. Best is to do this from a separate root, or a rescue/boot
disk, in which case rsync -av /oldroot/ /newroot/ is easy enough without
having to care.


PS: sick people will tell you to use tar with loads of pipes, or cpio,
don't listen to them ;)
