We are looking into replacing Lektor altogether in
TPA-RFC-37 (tpo/web/team#42), so it is better to stop working on this
as it's a significant undertaking.

We can reopen this discussion if we decide to stick with Lektor in the
end.

Closes: tpo/web/team#28

I couldn't find it the first time.

We don't have the cycles to process this right now, and al made a good
point that major donors specifically want this product, so we'd be
hard-pressed to just ditch it. It feels like a waste of time.

Closes: tpo/web/donate-static#75

This enables a new capability for which support was added in Ganeti
3.0.0: postcopy-ram migration support. Enabling this flag allows Ganeti
to automatically switch to postcopy-ram when precopy-ram migration is
not completing fast, allowing us to migrate very busy machines much more
rapidly and without human intervention (eg. no need to SIGSTOP gitlab
processes when migrating gitlab-02).

This is mostly so I can document the new ~Survey tag in GitLab.

I just upgraded a workstation to bookworm by mistake like this. Oops.

it is more readable that way

Closes team#40853

This mainly adds an upgrade howto to facilitate continuing upgrades of
this service.

This reverts commit bfd312ed.

This is a test of issue templates to see if the default templates work
and if issue templates work at all. Unless there are project
changes (which I won't do now), this should only affect the wiki
replica...

See team#29398.

An "alert" is not necessarily delivered through bots and email and
everything: it *could* be just a message on a dashboard, which is
actually a scenario I am considering.

In particular, I am considering the idea that we explicitly do *not*
want email notifications for TPA services, because those create a lot
of noise and are not necessarily useful for figuring out what's going
on (as opposed to a dashboard).

In any case, it seems important to decouple those two notions, which
were kind of mixed up before. This should be clearer now.
