`doas` is a lighter alternative to `sudo` that "provide[s] 95% of the
features of `sudo` with a fraction of the codebase" [1]. I prefer it to
`sudo`, so I figured I would add a NixOS module in order for it to be
easier to use. The module is based off of the existing `sudo` module.

Add extraConfig option for the muc submodule.
Also move the global extraConfig before all components and
virtualhosts, because the manual states:
The configuration is divided into two parts. The first part is known as
the "global" section. All settings here apply to the whole server, and
are the default for all virtual hosts.
The second half of the file is a series of VirtualHost and Component
definitions. Settings under each VirtualHost or Component line apply
only to that host.
Before, if at least one muc was defined, or uploadHttp enabled, the
global extraConfig would end up after "muc" or "http_upload" component
making it apply to that component only and not globally.
We add a Prosody entry to the NixOS manual showing how to setup a
basic XEP-0423 compliant Prosody service. This example also showcase
how to generate the associated ACME certificates.
Note: The <programlisting> body might look poorly indented, but trust
me, it's necessary. If we try to increase their indentation level, the
HTML output will end up containing a lot of unecesseray heading spaces
breaking the formatting...
This reverts commit 764c8203b8.
While this is desireable in principle, some of our modules and services
fail during service startup if no network is available don't currently
properly set Wants=network-online.target.
If nothing pulls in this target anymore, systemd won't try to reach it.
We have many VM tests waiting for `network-online.target`, and after
764c8203b8 fail with the following error
message:
```
error: unit "network-online.target" is inactive and there are no pending jobs
```
Most likely, test scripts shouldn't wait for `network-online.target` in
first place (as `network-online.target` says nothing about whether a
service has been started), but instead, the script should wait for the
network ports of the corresponding service to be open.
Let's revert this for now, and re-apply in a draft PR, fixing the tests
before merging it back in.
The output file is found and handled by thelounge itself [1], leaving
the user free to override THELOUNGE_HOME in the environment if they
choose, but having a sensible default to make `thelounge` generally
usable in most cases.
This solution follows discussion on #70318.

This follows upstreams change in documentation. While the `[DHCP]`
section might still work it is undocumented and we should probably not
be using it anymore. Users can just upgrade to the new option without
much hassle.
I had to create a bit of custom module deprecation code since the usual
approach doesn't support wildcards in the path.
You can now specify option for the `[DHCPv6]` section with
`systemd.network.<name>.dhcpV6Config.…`. Previously you could only use
the combined legacy DHCP configuration.
Systemd upstream has deprecated CriticalConnection with v244 in favor of
KeepConnection as that seems to be more flexible:
The CriticalConnection= setting in .network files is now deprecated,
and replaced by a new KeepConfiguration= setting which allows more
detailed configuration of the IP configuration to keep in place.
We are leveraging the systemd sandboxing features to prevent the
service accessing locations it shouldn't do. Most notably, we are here
preventing the prosody service from accessing /home and providing it
with a private /dev and /tmp.
Please consult man systemd.exec for further informations.
Setting up a XMPP chat server is a pretty deep rabbit whole to jump in
when you're not familiar with this whole universe. Your experience
with this environment will greatly depends on whether or not your
server implements the right set of XEPs.
To tackle this problem, the XMPP community came with the idea of
creating a meta-XEP in charge of listing the desirable XEPs to comply
with. This meta-XMP is issued every year under an new XEP number. The
2020 one being XEP-0423[1].
This prosody nixos module refactoring makes complying with XEP-0423
easier. All the necessary extensions are enabled by default. For some
extensions (MUC and HTTP_UPLOAD), we need some input from the user and
cannot provide a sensible default nixpkgs-wide. For those, we guide
the user using a couple of assertions explaining the remaining manual
steps to perform.
We took advantage of this substential refactoring to refresh the
associated nixos test.
Changelog:
- Update the prosody package to provide the necessary community
modules in order to comply with XEP-0423. This is a tradeoff, as
depending on their configuration, the user might end up not using them
and wasting some disk space. That being said, adding those will
allow the XEP-0423 users, which I expect to be the majority of
users, to leverage a bit more the binary cache.
- Add a muc submodule populated with the prosody muc defaults.
- Add a http_upload submodule in charge of setting up a basic http
server handling the user uploads. This submodule is in is
spinning up an HTTP(s) server in charge of receiving and serving the
user's attachments.
- Advertise both the MUCs and the http_upload endpoints using mod disco.
- Use the slixmpp library in place of the now defunct sleekxmpp for
the prosody NixOS test.
- Update the nixos test to setup and test the MUC and http upload
features.
- Add a couple of assertions triggered if the setup is not xep-0423
compliant.

Not all systems need to be online to boot up. So, don’t pull
network-online.target into multi-user.target. Services that need
online network can still require it.
This increases my boot time from ~9s to ~5s.
