Copying kernel and OS

[Paul T. Root]

It should work fine. You need to preserve mod and access
times as well as flags and permissions.

If you are going to do this on a repeated basis, I'd look
into something like cvsup or rsync, maybe even mirror, to
keep the slow machines directory structures in sync rather
than a cp -Rp.

Paul.
