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.
- Replace misleading docs.
- Add new assertions to let configurations make more sense.
- Add clusterInit flag.
- Add some more docs about HA and non-HA modes setup.
- Improve multi-node tests for HA mode.

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.
Setting `cgroup-driver=systemd` was originally necessary to match with
docker, else the kubelet would not start (#111835)
However, since then, docker support has been dropped from k3s (#177790).
As such, this option is much less necessary.
More importantly, it now seems to be actively causing issues. Due to an
upstream k3s bug, it's resulting in the kubelet and containerd having
different cgroup drivers, which seems to result in some difficult to
debug failure modes.
See
https://github.com/NixOS/nixpkgs/issues/181790#issuecomment-1188840862
for a description of this problem.
Removing this flag entirely seems reasonable to me, and it results in
k3s working again on my machine.
--port and --address have both been deprecated and are nonfunctional
starting with kubernetes 1.23. Use --secure-port and --bind-address
instead. This means that users can no longer rely on the insecure port
for anything, so update the release notes accordingly.
this set almost certainly shouldn't be touched by users, nor listed in
the manual. make it internal and use it only through the option path to
make clear that this should not be modified.
some options have default that are best described in prose, such as
defaults that depend on the system stateVersion, defaults that are
derivations specific to the surrounding context, or those where the
expression is much longer and harder to understand than a simple text
snippet.
