we can't embed syntactic annotations of this kind in markdown code
blocks without yet another extension. replaceable is rare enough to make
this not much worth it, so we'll go with «thing» instead. the module
system already uses this format for its placeholder names in attrsOf
paths.
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.
This removes the `services.dbus.socketActivated` and
`services.xserver.startDbusSession` options. Instead the user D-Bus
session is always socket activated.
DBus seems to resolve user IDs directly via glibc, circumventing nscd. In more
advanced setups this leads to user's coming from LDAP or SSSD not being
resolved by the dbus system bus daemon. The effect for such users is, that all
access to the system bus (e.g. busctl or nmcli) is denied.
Adding the respective NSS modules to the service's environment solves the issue
the same way it does for nscd.
DBus daemon now loads its config from /run/current-system/dbus.
Reloading the daemon makes it re-read that file and catch the updates
after a system upgrade.
The following changes are included:
1) install user unit files from upstream dbus
2) use absolute paths to config for --system and --session instances
3) make socket activation of user units configurable
There has been a number of PRs to address this, so this one does the
bare minimum, which is to make the functionality available and
configurable but defaults to off.

It appears that packageOverrides no longer overrides aliases, so
aliases like
dbus_tools = self.dbus.out;
dbus_daemon = self.dbus.daemon;
now use the old, non-overriden version of dbus. That seems like a
pretty serious regression in general, but for this particular problem,
I've fixed it by replacing dbus_daemon by dbus.daemon and dbus_tools
by dbus.
The docstring for the `services.dbus.packages` configuration option only
mentioned one directory, but the implementation actually looked for DBus
config files in four separate places within the target packages. This
commit updates the docstring to reflect the actual implementation
behaviour.
This patch makes dbus launch with any user session instead of
leaving it up to the desktop environment launch script to run it.
It has been tested with KDE, which simply uses the running daemon
instead of launching its own.
This is upstream's recommended way to run dbus.
Specifically, this fixes dnsmasq, which failed with
Apr 16 19:00:30 mandark dnsmasq[23819]: dnsmasq: DBus error: Connection ":1.260" is not allowed to own the service "uk.org.thekelleys.dnsmasq" due to security policies in the configuration file
Apr 16 19:00:30 mandark dnsmasq[23819]: DBus error: Connection ":1.260" is not allowed to own the service "uk.org.thekelleys.dnsmasq" due to security policies in the configuration file
after being enabled, due to dbus not being reloaded.
Many bus clients get hopelessly confused when dbus-daemon is
restarted. So let's not do that.
Of course, this is not ideal either, because we end up stuck with a
possibly outdated dbus-daemon. But that issue will become irrelevant
in the glorious kdbus-based future.
Hopefully this also gets rid of systemd getting stuck after
dbus-daemon is restarted:

Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.
