Hi!
On systems like linux, cp / -a --one-file-system (destination) will
not copy whole root filesystem. It is not cp's fault, but the
behaviour is quite surprising to the users, so maybe it would be worth
warning in man page?
Something like
-x, --one-file-system
stay on this file system
Note that on systems that allow mounts over non-empty
directories (like Linux), cp / -ax (destination) will
not copy whole filesystem. In particular, content of
/dev will not be usually copied, because distributions
mount tmpfs over /dev.
[Ok, there's hopefully better wording...?]
