I imagine there's relatives like the programmer beard, but googling "UNIX
beard" returns some examples where it seems to be a thing.

We all know and love the UNIX beard, but I
can't find anything on how
the beards started other than an old photo of Ken and Dennis
I'm not sure the term is Unix-specific. At a fairly early stage, people who
worked on the ARPANET/Internet (when PDP-10's were still the 'usual'
host,
and
Unix systems were just starting to beceome common) were jokingly known as
'network grey-beards': the prototypical one being Jon Postel. (Vint
Verf's
beard was too tidy to qualify, IIRC!)
