The switch from slim to lightdm in #30890 broke some nixos tests
because lightdm by default doesn't permit auto-login for root.
Override /etc/pam.d/lightdm-autologin to allow it.
What annoyed me for a long time was the fact, that in order to break
into a new paragraph, you need to insert </para><para> in the
description attribute of an option.
Now we will automatically create <para/> elements for every block that
is separated by two consecutive newlines.
I first tried to do this within options-to-docbook.xsl, but it turns
out[1] that this isn't directly possible with XSLT 1.0, so I added
another XSLT file that postprocesses the option descriptions that are
now enclosed in <nixos:option-description/> by options-to-docbook.xsl.
The splitting itself is a bit more involved, because we can't simply
split on every \n\n because we'd also split text nodes of elements, for
example:
<screen><![CDATA[
one line
another one
]]></screen>
This would create one <para/> element for "one line" and another for
"another line", which we obviously don't want because <screen/> is used
to display verbatim contents of what a user is seeing on the screen.
So what we do instead is splitting *only* the top-level text nodes
within the outermost <para/> and leave all elements as-is. If there are
more than one <para/> elements at the top-level, we simply don't process
it at all, because the description then already contains </para><para>.

Out of bounds vulnerability in versions up to 0.62.
Generally, we use a newer poppler version but some pkgs still depend on
0.61. Patch named in https://nvd.nist.gov/vuln/detail/CVE-2018-13988.
The switch to lightdm as default display manager in #30890
broke eval of the flatpak test. Since the test uses the
auto display manager (lightdm), gdm must now be explicitly disabled.
The option was added in 1251b34b5b
with type `types.path` but default `null`, so eval failed with
the default setting. This broke the acme and certmgr tests.
