Between the two procedures Thomas gave you, "fetch & rebase" is
safer than "fetch & reset --hard", exactly because it does not have
to rely on the validity of your "which should always be behind"

If it is behind, there won't be any difference, but if it is *not*,
the user will notice and won't lose his work on 'master' (which you
may argue that he shouldn't have done).  "rebase" will notice it.

The key for a procedure to be safe is not having to rely on the
claim of users such as "my history *should* always and already be
behind", and not silently lose information when these *should*s are
violated for whatever reason.  After all, if all these *should*s
were true, the user wouldn't have been having problems in the first
place and posting to the list asking for help in the first place ;-)
