I'm not sure we would solve anything by registering them.

Unlike NFS, where we run on non-standard ports, using registered prognums and progvers lets us advertise via portmapper to clients what port(s) to use for mountd, nfs, and nlm services.

If we ever intend to run glusterd on a port other than 24007, and advertise through portmapper, then I could imagine there would be some value in registering our prognums and progvers.

But we don't advertise in portmapper, and AFAIK, we're not planning to use any port other than 24007 (and 24009+)

I presume we've registered port 24007 at least with IANA. If not, we should.
