All activation scripts run in serial upon boot and nixos-rebuild switch
etc., in contrast to preStart which run before a service starts, and can
run in parallel with other services.
The munin(-node) activation script is particularly slow. Change it to a
preStart script so that it can run in parallel with other services and
not slow down boot (or nixos-rebuild switch).
This reduces (repeated) "nixos-rebuild test" time from ~16 seconds to ~8
on my (old) laptop.
This is due to breaking evaluation; see the PR discussion.

Two imports were added independently on the same line.
I split it as well, as it was very long now.
Commit 89fee1006c ("nixos/redis: clean up
option types") broke nixos evaluation:
error: attempt to call something which is not a function but a set, at .../nixpkgs/nixos/modules/services/databases/redis.nix:111:28
Fix it.
Reported by Oliver Charles (thanks!).
Apart from s/types.string/types.str/ (or types.lines where appropriate):
* port is changed from string to int.
* extraFlags is changed from types.string (with unfortunate merge
semantics) into a list of strings. A list of strings merge better:
one space is added between elements.
This reverts commit a3331eb87b.
See https://github.com/NixOS/nixpkgs/issues/2559#issuecomment-47313334
for a description why this is not a good idea.
I guess it's better to implement a sane way to remove all files in
authorized_keys.d, especially because it is also backwards-compatible.
Reopens#2559.

- Expose mainConfigFile and cgiConfigFile in module for finer
configuration control.
- Upgrade Plugins to 2.x
- Remove default objectDefs, which users probably want to customize.
- Systemd-ify Nagios module and simplify directory structure
- Upgrade Nagios package with more modern patch, and ensure the

music_directory "${cfg.musicDirectory}"
playlist_directory "${cfg.dataDir}/playlists"
db_file "${cfg.dataDir}/tag_cache"
state_file "${cfg.dataDir}/state"
sticker_file "${cfg.dataDir}/sticker.sql"
all refer to ${cfg.datadir}, which by default is "/var/lib/mpd/".
Parsing for instance ${cfg.datadir}/playlists results in:
/var/lib/mpd//playlists - NOT FOUND.
Currently, the restartTriggers are abusing the systemd unit file in that
the cfg.carbon.config/storageAggregation/... option text is pasted into
the unit file. Even though this sort-of works (the service is restarted
if the config changes) this causes systemd to print error messages about
invalid sections (rightfully so!).
The correct use of restartTriggers is to list storage paths, which is
what this change does. If any of the
cfg.carbon/config/storageAggregation/... options change, configDir will
get a new hash. It is not as "fine grained" as the current version, but
it is not abusing the interface.
Also, remove unneeded 'waitress' in one of the restartTriggers, because
it is already listed as part of the service config.
graphitePort must point to the port that carbon-cache listens on, not
the graphite webUI port.
With this change I finally got data from statsd to graphite.
It's "aggregation" with two 'g's.
Fixes this:
carbon-cache[9363]: [console] /nix/store/drxq4jj92sjk3cjik2l4hnsndbray3i4-graphite-config/storage-aggregation.conf not found, ignoring.
One reason for adding this is to make Chromium able to open files it has
downloaded.
Currently this happens:
/run/current-system/sw/bin/xdg-open: line 364: gnome-open: command not found
(And nothing happens in the GUI when clicking a downloaded file.)
Looking into xdg-open, one can see that it first tries to run gvfs-open
and then falls back to gnome-open. Adding 'gvfs' makes the first command
succeed.

This overhauls the Datadog module a bit to be much more useful. In
particular, it adds support for nginx and postgresql monitoring
integrations to dd-agent. These have to exist in separate files under
/etc/dd-agent, so the module just exposes then as separate options. In
the future, more integrations could be added this way.
In the process of doing this, I also had to rename the dd-agent user to
datadog. Note the UIDs did not change, so this is strictly backwards
compatible. The reason for this is to make it easier to create a
'datadog' postgres user with access to pg_stats, as 'dd-agent' typically
isn't a valid username. This allows the out of the box configurations to
be used.

Previously all card-specific stuff was scattered across xserver.nix
and opengl.nix, which is ugly. Now it can be kept together in a single
card-specific module. This required the addition of a few internal
options:
- services.xserver.drivers: A list of { name, driverName, modules,
libPath } sets.
- hardware.opengl.package: The OpenGL implementation. Note that there
can be only one OpenGL implementation at a time in a system
configuration (i.e. no dynamic detection).
- hardware.opengl.package32: The 32-bit OpenGL implementation.
Fixes#2379.
The new name was a misnomer because the values really are X11 video
drivers (e.g. ‘cirrus’ or ‘nvidia’), not OpenGL implementations. That
it's also used to set an OpenGL implementation for kmscon is just
confusing overloading.
The Tarsnap module is now far more flexible, allowing individual
archives with individual options to be specified at will, allowing
granular backup schedules, etc.

This fixes several problems in the dhcpcd service:
* A segfault during startup, due to a race with udev (dhcpcd would get
an ADD event from udev, causing it to re-add an interface that it
already had, leading to a segfault later on).
* A hang/segfault processing "dhcpcd rebind" (which NixOS calls after
waking up from suspend).
Also, add "lo" to the list of ignored interfaces. It usually ignores
"lo", but apparently not when it gets an ADD event from udev.
By enabling ‘services.openssh.startWhenNeeded’, sshd is started
on-demand by systemd using socket activation. This is particularly
useful if you have a zillion containers and don't want to have sshd
running permanently. Note that socket activation is not noticeable
slower, contrary to what the manpage for ‘sshd -i’ says, so we might
want to make this the default one day.
This causes OpenVPN services to reach the "active" state when the VPN
connection is up (i.e., after OpenVPN prints "Initialization Sequence
Completed"). This allows units to be ordered correctly after openvpn-*
units, and makes systemctl present a password prompt:
$ start openvpn-foo
Enter Private Key Password: *************
(I first tried to implement this by calling "systemd-notify --ready"
from the "up" script, but systemd-notify is not reliable.)
The ability for unprivileged users to mount external media is useful
regardless of the desktop environment. Also, since udisks2 is
activated on-demand, it doesn't add any overhead if you're not using it.
This led to the container test failing, which made no sense
whatsoever, until I realized nix-daemon.socket creates the socket
directory as a side effect, which systemd-nspawn then bind-mounts.

This has some advantages:
* You get ssh-agent regardless of how you logged in. Previously it was
only started for X11 sessions.
* All sessions of a user share the same agent. So if you added a key
on tty1, it will also be available on tty2.
* Systemd will restart ssh-agent if it dies.
* $SSH_AUTH_SOCK now points to the /run/user/<uid> directory, which is
more secure than /tmp.
For bonus points, we should patch ssh-agent to support socket-based
activation...
If you define a unit, and either systemd or a package in
systemd.packages already provides that unit, then we now generate a
file /etc/systemd/system/<unit>.d/overrides.conf. This makes it
possible to use upstream units, while allowing them to be customised
from the NixOS configuration. For instance, the module nix-daemon.nix
now uses the units provided by the Nix package. And all unit
definitions that duplicated upstream systemd units are finally gone.
This makes the baseUnit option unnecessary, so I've removed it.
mkdir -m will only set the permissions if it *creates* the directory.
Existing directories, with possibly wrong permissions, will not be
updated.
Use explicit chmod so permissions will always be correct.
The preStart snippets (graphite, carbon) try to create directories under
/var/db/. That currently fails because the code is run as user
"graphite". Fix by setting "PermissionsStartOnly = true" so that the
preStart stuff is run as 'root'.
Further:
* graphite-web-0.9.12/bin/build-index.sh needs perl, so add it to PATH.
* Now that preStart runs as root, we must wait with "chown graphite"
until we're done creating files/directories.
* Drop needless check for root (uid 0) before running chown.
