Absolute paths are bad news here.  Especially when
dealing with an rsync daemon.  This allows the user to
defeat any location restrictions.  Not only working outside
the module of an rsync daemon but also the kinds of
restrictions that someone might set up using command=
wrappers in ssh.

That's good at least temporarily, probably permanently.
