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.

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.
Using /etc/lighttpd.conf "hides" the config file from NixOS so that it
will not automatically restart the service when its config file changes.
So don't do that.
I think it's nice that it first asks the usual password, and then offers the
otpw one if enabled. That enables dovecot to show the last pam prompt.
I also add the dovecot option for that.
Previously we synced just before calling switch-to-configuration.
That prevents corruption of the Nix store, but it can leave the boot
loader configuration and kernel files in /boot corrupted. So do the
sync after installing the boot loader.
Usually timers.target is pulled in by basic.target, but we don't
restart basic.target. So timers.target wouldn't be started when
coming from an older systemd.
This allows Xen (and EC2) to power off an instance properly. We had
this before (see aeb89fc753c6f95c9d143e6f5346f92e4a02fa67), but it got
lost in the systemd migration.
Now that nixUnstable supports remounting in the "/nix/store is a
mountpoint" case, this is no longer necessary.
