This sent me down the path of realizing the hostname executable wasn't
installed on the Arch VM I'm trying to bind to the domain. I've had
problems with this in the past (Vagrant won't work unless you install
the pre-historic route executable), but unfortunately installing
hostname (the inetutils package) didn't fix the problem.
Summarizing DNS issues when binding a computer to the domain:
# samba-tool domain join ea.linuxcs.com MEMBER -U administrator
--> A and PTR records are not created for the client host
# net ads join -U administrator
--> A record is created, but not the PTR record
On Arch linux I can't find the magic incantation which even creates the
A record. None of this is a big deal, but it is inconvenient, and it
raises the question of how this works, which is what I'm curious about.
