Biggest problem is overwriting your existing UID's and GID's.

If you already have files on the secondary system which are owned by UID
650, and your replaced passwd files don't _have_ a UID 650, then you'll
have some holes in your file system as far as ownerships etc go.

But if you're running a complete duplicate down to user files, then there
shouldn't be any problems.
