My google fu quickly turned up this info:
https://unix.stackexchange.com/questions/564673/wheres-my-stub-resolve-conf-missing
which suggests that I need to start systemd-resolved.service.
However, since this is an AD DC, I want samba to provide the DNS. So I've
disabled systemd-resolved.service.
I suppose that the anti-systemd crowd will go into fits about this. Does
anyone have a solution?
Thanks,
Jonathan Kreider
