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.
Without this, if the network goes down for a while, systemd will give up after 5 restarts:
Scheduled restart job, restart counter is at 5.
Stopped Nebula VPN service for myvpn.
nebula@myvpn.service: Start request repeated too quickly.
Failed with result 'exit-code'.
Failed to start Nebula VPN service for myvpn.
Most network services need this, but for VPNs it's extra important.
