If I want to bring down tap0.service (or systemd wants to do this
during a configuration-change which changes the path to tunctl),
openvpn (or other services using tap0) need to be brought down as
well, otherwise tunctl -d is not able to remove the tap0 device,
leaving it in a failed (but "up") state.
"require" is a stronger version of "want",
and just like wantedBy allows you to specify this relation in reverse,
requiredBy does the same.
It may seem pointless to be able to specify these stronger relations in
reverse, because if something is really required, you would expect the
other unit to specify this himself.
However, this is still useful for virtual/automatic units (like
devices) that are created by systemd on demand and hence have no unit
file you can alter.
This reverts commit 7f1e728606.
This would have been nice if we had had it from the start, but now it
just breaks things for existing users. Maybe we can add it conditionally
when new postgres versions come out.

desktop-manager is a bit misleading in this case as there is no
session yet and most apps are still missing. This can eventually
grow further once more e17 apps get packaged for nix.
However, for now, I need to initialize some e17 dbus services to
have the "terminology" terminal emulator provide gfx previews.
The user should specify which major version to use
(e.g. "services.postgresql.package = pkgs.postgresql92"). We can't
really provide a sensible default, because such a default would have
to be updated from time to time, and there is no automated upgrade
procedure. So leave upgrading to the user.
Enabling udisks2 allows gvfs (which should be built with udisks support) to
perform mount/unmount operations on removable drives. It affects Thunar and
probably other Gtk-based file managers.
Gvfs doesn't supports earlier versions of udisks.
As @edolstra pointed out, this behavior is not equivalent to what we had
before as the kernel command line parameter won't take effect until the
next boot. Probably it's not likely that someone will make this change
and then add a network card before rebooting, but might as well support
that since we can.
This reverts commit f7563698df.

Sometimes nscd starts up before a /etc/resolv.conf file has been written, and
apparently triggering a cache flush (reload) is not good enough to make it
recover from that problem. To remedy the issue, we restart the service instead.
See <https://github.com/NixOS/nixos/issues/34> for further details.
