If socket activation is enable (the default) and printers are configured
declaratively, the ensure-printers service will always start cupsd and
leave it running, thus defeating the point of socket activation.
With this change ensure-printers continues to start the cups.service at
boot, but automatically stops it afterwards if socket activation is
enabled.
Note: Later restarts of ensure-printers will also restart cupsd, but
it's not an issue since it will be reactivate, if necessary.
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.
It's `lib.versions`, not `lib.version`. Also I'm really sure that it's
supposed to be the current version of Gutenprint, not Cups, as thats
what `lpinfo -m` says on my system.
