Having socket-activated epmd means that there always be only a single
instance managed centrally. Because Erlang also starts it
automatically if not available, and in worst case scenario 'epmd' can
be started by some Erlang application running under systemd. And then
restarting this application unit will cause complete loss of names in
'epmd' (if other Erlang system are also installed on this host).
E.g. see at which lengths RabbitMQ goes to recover from such
situations:
7741b37b1e/src/rabbit_epmd_monitor.erl (L36)
Having the only one socket-activated epmd completely solves this
problem.
This makes the command ‘nix-env -qa -f. --arg config '{skipAliases =
true;}'’ work in Nixpkgs.
Misc...
- qtikz: use libsForQt5.callPackage
This ensures we get the right poppler.
- rewrites:
docbook5_xsl -> docbook_xsl_ns
docbook_xml_xslt -> docbook_xsl

This allows non-privileged users to configure local DNS
entries by editing hosts files read by NetworkManager's dnsmasq
instance.
Cherry-picked from e6c3d5a507 and

The deep merge caused all the options to be unset when generating docs, unless quagga was enabled.
Using imports, instead, properly allows the documentation to be generated.
The `.service` file defining the `systemd` unit for `autorandr.service`
which is bundled with the package itself uses `--default default` in the
`ExecStart` section. This can be an issue when having multiple layouts
(e.g. `default` as workstation layout I mostly work on and `mobile` when
I go somewhere else).
When the service gets restarted and `--default` can't be applied,
however the current layout can't be detected (e.g. when working with an
unknown beamer) the service silently fails with a message like this:
```

As discussed in the IRC (see https://botbot.me/freenode/nixos/2018-07-05/?msg=101791455&page=6)
it's a bad long-term solution in terms of maintenance to manually patch
the service file bundled with the derivation, instead the service shall
be configured declaratively. Additionally this makes possible overrides
from the user-space way easier.
The `udev` rule (in `$out/etc/udev/rules.d`) won't' be affected, it
simply runs `systemctl start autorandr.service` when e.g. a new display
is added, so now `udev` communicates with the NixOS systemd unit.
To update the plasma start menu `kbuildsyscoca5` needs to be executed.
There are several people complaining about missing applications in their
plasma start menu.
This patch adds a activationScript for plasma, that runs
`kbuildsyscoca5` for each user that has `isNormalUser` == `true`.
In fff5923686 all occurences of
users.extraUsers and users.extraGroups have been changed tree-wide to
users.users and users.group. In the meantime the hadoop modules were
introduced via #41381 (060a98e9f4).
Unfortunately those modules still use users.extraUsers, which has been
renamed a long time ago (14321ae243, about
three years from now), so let's actually rename it accordingly as well.
