The firefox diffoscope output requires unzip for making the diff
readable.

The gitlab logs are enormous, spammy and are half a terabyte per month.

Node's address lookup strips the scope ID from link-local IPv6
addresses, making them invalid and unable to be connected to.

We're getting hit with this since Node 17 because it now defaults to the
`verbatim` dns-result-order and this happens to return the link-local
IPv6 address for `matrix.archlinux.org` first.

Specify `ipv4first` so we return to Node 16's behavior.

Loki v2.4.0 introduced a common config section[1][2] making the config
much smaller and better defaults.

So stripped loki.yaml down, removed options where the default is "good
enough" and tweaked retention settings per the upgrade notes[3].

So the config should basically be the example loki.yaml[4] + compactor,
retention enabled and a few tweaks (ex: compress chunks with zstd).

This reverts commit 5c4ff7af.

The account migration is done, so offsite backups can be re-enabled.

New username; separate and longer account manager + storage passwords.

Also, have to use --remote-path=borg1 when interacting with rsync.net.

Increase default time range from 90 days to 6 months.

rsync.net is about to migrate us to a new username/hostname pair.

This was a regression which has been fixed upstream.

This reverts commit 67e7677e.

We're no longer allowed to reserve formerly used namespaces.
