note: systemd has rpcbind socket, removing that variable had no effect.

But I noticed rpcbind is running as _rpc user in the non-working
environments.
There was a major change in rpcbind from affected versions.
And… finally:
(c)rafaeldtinoco@groovy:~$ rup
bionic.lxd 12:56 up 18:31, load 0.22 0.16 0.10
groovy.lxd 12:56 up 12:51, load 0.22 0.16 0.10
xenial.lxd 12:56 up 18:26, load 0.22 0.16 0.10
I had to replace groovy rpcbind with rpcbind from bionic.
Now, in some other time, I'll have to check what changes to rpcbind (a
lot) made this happen.
