I'm really not sure who, and under what circumstances,
hostnamectl is for. I ran:

# hostnamectl set-hostname acerx

and /etc/hostname was changed, but not /etc/hosts, which still had:

127.0.1.1       acer.corp       acer

and also not /etc/mailname. I'm not saying it should have affected
those occurrences, but that it's better to check you have the
correct, consistent name throughout the system.

It's also not clear to me either, where one might insert this command
so that it takes effect early enough to avoid polluting the system
with wrong names. (The logs, for one example.)

It would seem then that you were letting DHCP in the router set your
hostname as well as the usual IP address, nameservers etc, which
could be unfortunate if it doesn't agree. How you avoid that depends ….

Cheers,
David.
