make (almost) all links appear on only a single line, with no
unnecessary whitespace, using double quotes for attributes. this lets us
automatically convert them to markdown easily.
the few remaining links are extremely long link in a gnome module, we'll
come back to those at a later date.
our xslt already replaces double line breaks with a paragraph close and
reopen. not using explicit para tags lets nix-doc-munge convert more
descriptions losslessly.
only whitespace changes to generated documents, except for two
strongswan options gaining paragraph two breaks they arguably should've
had anyway.
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 change, configurations like
```nix
fileSystems."/path/to/bindMountedDirectory" = {
device = "/path/to/originalDirectory";
options = [ "bind" ];
};
```
will lead to a warning message in `dmesg`:
```
systemd-fstab-generator: Checking was requested for "/path/to/originalDirectory", but it is not a device.
```
This happens because the generated /etc/fstab entry contains a non-zero fsck pass number, which doesn't make sense for a bind mount.
Tell zpool-list(8) to format output rather than modifying it afterwards.
Furthermore, pool names may contain spaces and would thus break due to
awk(1)'s word splitting.
Although unlikely, ZFS happily accepts names like 'zroot/foo -r'.
Escape names and separate command line options from arguments to avoid
any kind of misinterpretation.
Previously this wasn't done in the `forEach`-expression for
`cfg.interfaces` and thus `networking.useDHCP` didn't have any effect if
no further interface was statically configured.
This includes disabling some features in the initrd by default, this is
only done when the new initrd is used. Namely, ext and bcache are
disabled by default. bcache gets an own enable option while ext is
detected like any other filesystem.
