I'm not aware of any variety of Linux or BSD where the "mv" command
can't handle moving a file to a different filesystem.

I think the real issue is that with "mv", a copy of the log
would no longer be in the working directory, which is only
an issue if Bro had crashed (that's when post-terminate
runs archive-log with the "-c" option, which indicates that
we shouldn't remove the log after archiving it).
