Investigate disk space on trunk.social.coop, we may be running low.

As noticed by @fardog in #13 (closed), disk space on trunk is low.

After he pruned the docker images, recovered the server and rebooted, the disk space is now 90% full on the root partion (which contains the docker filesystem, and that occupies most of this) and vol2 is 64% full (which contains the Postgres database and backups thereof).

df -h
Filesystem      Size  Used Avail Use% Mounted on
none            3.9G     0  3.9G   0% /dev
tmpfs           794M   23M  772M   3% /run
/dev/nbd0        46G   39G  4.7G  90% /
tmpfs           3.9G  8.5M  3.9G   1% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           3.9G     0  3.9G   0% /sys/fs/cgroup
/dev/nbd1        46G   28G   16G  64% /var/vol2

See the notes in #13 (closed) for more stats.

It may be that we have to get more disk space, and this will require paying for it.
