I've never had a problem on systems that have GNU cp (i.e. Linux) using
'cp --one-file-system -a ...' to copy complete filesystems as exactly
as possible. 'rsync --one-file-system -aH ...' will work too. I'm
not sure if anyone mentioned that that file-oriented copies: tar,
cpio, cp, rsync, etc. allow the target to be on a different filesystem
type than the source, while dump does not, and dd reproduces the
original filesystem.
