Injecting configuration specific dependencies into the
propagatedBuildInputs of the home-assistant package forces alot of
rebuilds while setting up home-assistant, which is annoying.
By passing optional dependencies into home-assistant via the systemd
units PYTHONPATH environment variable, only he concatenation of
library paths in the systemd unit requires a rebuild.
This also means users can rely heavily on the cached home-assistant
package and will rarely have to build from source, if ever.
In some recent version evcc started requiring `getent` in the PATH, or
else it would fail to start.
It also now requires an sqlite database, which it tries to create a
directory for at `$HOME/.evcc`, so we now need to provide a
StateDirectory.
The tests would fail after migrating to `buildNpmPackage`, likely
because we are now using nodejs 18.

conversions were done using https://github.com/pennae/nix-doc-munge
using (probably) rev f34e145 running
nix-doc-munge nixos/**/*.nix
nix-doc-munge --import nixos/**/*.nix
the tool ensures that only changes that could affect the generated
manual *but don't* are committed, other changes require manual review
and are discarded.
this renders the same in the manpage and a little more clearly in the
html manual. in the manpage there continues to be no distinction from
regular text, the html manual gets code-type markup (which was probably
the intention for most of these uses anyway).
A larger number of bluetooth components were introduced in 2022.8.0. To
make them work we need to add a hardening exception, so they can
discover and use bluetooth devices.
the conversion procedure is simple:
- find all things that look like options, ie calls to either `mkOption`
or `lib.mkOption` that take an attrset. remember the attrset as the
option
- for all options, find a `description` attribute who's value is not a
call to `mdDoc` or `lib.mdDoc`
- textually convert the entire value of the attribute to MD with a few
simple regexes (the set from mdize-module.sh)
- if the change produced a change in the manual output, discard
- if the change kept the manual unchanged, add some text to the
description to make sure we've actually found an option. if the
manual changes this time, keep the converted description
this procedure converts 80% of nixos options to markdown. around 2000
options remain to be inspected, but most of those fail the "does not
change the manual output check": currently the MD conversion process
does not faithfully convert docbook tags like <code> and <package>, so
any option using such tags will not be converted at all.
Overriding can now happen using module options, which is preferred
because it is more discoverable and doesn't require knowledge of
overrides in the first place.
While the documentation said to set this to null, in case an imperative
config was supposed to be used, this was not possible with the typing in
place.
Database provisioning was shown to be racy since adding a recorder test
using PostgreSQL. There is no harm in waiting for these services,
because if they're not available they will be ignored.
It simply should not be required to override the package for such a
common use case, especially since the module usually adds another
override on top to inherit extraComponents.
After this change users with non-declarative configs need to set
`services.home-assistant.config` to an `null`, or their
`configuration.yaml` will be overwritten.
The reason for this is that with rfc42 style defaults the config
attribute set will never be empty by default.
If people take the time to setup network-online.target correctly we
should wait for it. If they don't it's basically the same as
network.target anyway, so no harm done.
Over time I've seen multiple integrations that have dealt badly with
missing network connectivity at startup, this should alleviate further
pains.
The given example is now closer to a sane default people will want to
start with. It also displays the existance of extraComponents, a feature
that will receive more usage with home-assistant warning about
components that have completely migrated away from YAML configuration.
