The code isn't vulnerable to nginx alias traversal[1][2], nevertheless
it should only match /static/ and not e.g. /staticfoobar.

Whoosh is used by default, but it is slow at indexing (multiple hours
for just aur-requests) and searching e.g. aur-requests isn't possible
(it is slow and uses 3G+ of memory resulting in it getting OOM-killed).

Xapian indexed everything in just 76 minutes and searching aur-requests
now works and is plenty fast.

It has been decided not to migrate the following unlisted and unused
lists:
arch-magazine
arch-notifications
arch-test
mailman

The default (40KB) isn't enough for all patches.

It is cumbersome to manage the list configurations from the web ui and
easy for them to diverge, so let's instead manage them with Ansible.

Fix #254

Fixes: 26f289b7 ("Capitalize the first letter of all task names")

ansible-lint 6.5.0 complains about:

  name: All names should start with an
        uppercase letter. (name[casing])

We don't want our users tracked by a third party.

These are used to signal the start of the document in a stream of many
documents. As Ansible only supports one YAML document per file this is
unnecessary. About a third of our YAML documents already lacked these.

It is run as part of the nntp runner now[1].

mailman-web has been packaged in the community repo and it uses
different paths than my homebrewed PKGBUILD.

We want to migrate to mailman3 as mailman2 is basically unmaintained and
requires Python 2 which is EOL.

Because the mailman and mailman3 packages conflict and we don't want to
perform a big bang migration, mailman3 must be deployed on a separate
server. mailman-web (mailman3's web interface) hasn't been packaged yet,
so for now we are using my homebrewed PKGBUILD[1].
