greetings ~teammates!

ubuntu 20.04 focal fossa is now nearing the first point release and is 
ready for us to upgrade. 

i've been preparing a new vm for us with a couple long-term improvements
that i've been thinking about for a while. here are the major changes:

- dedicated /home disk - we haven't had any actual issues here luckily
  but it will prevent any issues where a user accidentally fills a disk
  and chokes out the rest of the system

- fixing uids - at some point, the spamassassin package created a system
  user account with a uid > 1000 which threw off the user numbering into
  the 5000 range. i've renumbered user accounts on the new vm to remove
  that large jump

the upgrade (migration?) plan is as follows:

- initial hot copy of the live system with rsync
- stop running services
- second cold copy with rsync including mariadb dump
- move IP addresses to new vm
- reboot
- profit?

i'll provide updates in #team (which you can access via webchat while
~team itself is down: https://kiwi.tilde.chat/#team) and post an update
to our status page: https://status.tilde.team/

let's hope it all goes smoothly and we'll see you on the other side :)

note that bsd.tilde.team will not be affected and is a good place to use
weechat from as well.

cheers,
~ben
