That's a good point. If we do go with using UUID's as the sole
representation internally, it might make sense to allow SysAdmins
to manipulate UUID's in useful ways.
Through the CLI, it could be something like this:
gluster1> $ sudo gluster peer updateuuid mypeername NEW-UUID-VALUE
peer alias update: success
BUT... I don't yet understand the failure modes that people have
mentioned around UUID's, so that's just an off-the-cuff thought
rather than a deeply-thought-out-with-appropriate-wisdom one. :)
