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.
Since https://github.com/NixOS/nixpkgs/pull/61321, local-fs.target is
part of sysinit.target again, meaning units without
DefaultDependencies=no will automatically depend on it, and the manual
set dependencies can be dropped.
While BOINC itself is open source, many of the project applications
it runs are not. Additionally, these project applications are
checksummed before they are run, so they can't be patched. This
means we can't make the project applications find required binaries/libraries
on a NixOS system. The solution is therefore to make said binaries
and libraries appear in the expected locations, by wrapping BOINC
in an FHS-compatible environment [1].
An `extraEnvPackages` is also added to allow more packages to
be added into this environment. The documentation for this option
describes some practical use cases for it.
