Yeah, this ain't funny, right? :-/

Today while I was working on the base-email and base-ssl fixes I noticed
that 5209R and 5210R *both* were doing unrequested hostname flips on their
own.

Here is a small excerpt from /var/log/messages that happened *just* when
turning SSL on or off for a Vsite:

systemd-hostnamed[1188684]: Changed static host name to '5210r.smd.net'
NetworkManager[904]: <info>  [1603944094.5183] hostname: hostname changed
from "5210r.smd.net" to "5210r"
NetworkManager[904]: <info>  [1603944094.5354] policy: set-hostname: set
hostname to '5210r' (from system configuration)
NetworkManager[904]: <info>  [1603944094.5358] hostname: hostname changed
from "5210r" to "5210r.smd.net"
systemd-hostnamed[1188684]: Changed host name to '5210r'
systemd[1]: Starting Network Manager Script Dispatcher Service...
NetworkManager[904]: <info>  [1603944094.5482] policy: set-hostname: set
hostname to '5210r.smd.net' (from system configuration)
systemd-hostnamed[1188684]: Changed host name to '5210r.smd.net'

Which is totally ridiculous, as no transaction was requested that should
mess with the servers hostname. I'm sure this is somehow related to your
issues as well.

I'll go digging and see what I find out.
