lighttpd doesn't support loading a module more than once. If you attempt
to load a module again, lighttpd prints an error message:
(plugin.c.131) Cannot load plugin mod_cgi more than once, please fix your config (we may not accept such configs in future releases
And it's not just the error message. The module isn't loaded (or is
messed up somehow) so that neither sub-service will work properly after
this.
This is bad news for the current approach to sub-services, where each
sub-service lists the needed modules in a server.modules += (...) block.
When two sub-services need the same module we get the above issue. (And,
AFAIK, there is no way to check if a module is already loaded either.)
First I thought about an approach where each sub-service specifies the
list of plugins it needs, and that a common server.modules = (...) list
is built from the union of those lists. That would loosly couple the
sub-services with the main lighttpd nixos module expression. But I think
this is a bad idea because lighttpd module loading order matters[1], and
the module order in the global server.modules = (...) list would be
somewhat cumbersome to control.
Here is an example:
Sub-service A needs mod_fastcgi. Sub-service B needs mod_auth and
mod_fastcgi. Note that mod_auth must be loaded *before* mod_fastcgi to
take effect. The union of those modules may either be ["mod_auth"
"mod_fastcgi"] or ["mod_fastcgi" "mod_auth"] depending on the evaluation
order. The first order will work, the latter will not.
So instead of the above, this commit moves the modules from
service.modules += (...) snippets in each sub-service to a global
server.modules = (...) list in the main lighttpd module expression. The
module loading order is fixed and each module is included only if any of
the sub-services that needs it is enabled.
The downside to this approach is that sub-services need a (tiny) bit of
change to the main lighttpd nixos module expression. But I think it is
the only sane way to do it (as long as lighttpd is written the way it
is).

This is because it's quite commonly used in the wild. Especially at some "weird"
server hosters (no names here) which doesn't allow to change the baudrate for
their serial consoles.

Starting with Zabbix 2.0 the order of data imports is important[*] and will lead
to errors if not done in the right order. Zabbix 1.8 works fine with the swapped
order as well, so this change shouldn't affect any pre-2.0 users.

Quoting from the manual about DBHost:
```
In case of MySQL localhost or empty string results in using a socket. In case of
PostgreSQL only empty string results in attempt to use socket.
```
https://www.zabbix.com/documentation/2.0/manual/appendix/config/zabbix_server
With this commit we should avoid some race conditions in systemd, because if the
host is set to "", there is no condition that postgresql has to be started prior
to the Zabbix server.

At least the Zabbix 2.x web installer requires max_input_time to be set to 300
seconds. As it doesn't hurt to set it for the 1.x versions, I'm including it
here.

This is to avoid (in some cases) constant restarting of the Zabbix server, which
causes odds bugs and crashes in the exit handler (if it's too early during
startup).

If we only need to generate a GRUB boot menu, we don't need GRUB
itself. This cuts 38 MiB from EC2 system closures (in particular
because it gets rid of the need for the 32-bit Glibc).
(cgit is "a hyperfast web frontend for git repositories written in C")
cgit is enabled like this (assuming lighttpd is already enabled):
services.lighttpd.cgit.enable = true;
and configured verbatim like this (contents of the cgitrc file):
services.lighttpd.cgit.configText = ''
cache-size=1000
scan-path=/srv/git
'';
cgit will be available from this URL: http://yourserver/cgit
In lighttpd, I've ensured that the cache dir for cgit is created if cgit
is enabled.
apparmor's systemd service wasn't working when multiple profiles were
defined, due to the ExecStart commands in the service file being
broken into multiple lines, instead of being separated by ';'.
This is what currently happens (from the journal log):
[/nix/store/HASH-unit/transmission.service:27] Executable path is not absolute, ignoring: kill -HUP $MAINPID
Fix it by using absolute path to kill.
1 minute is too short, given that the autovacuum launcher often seems
to require exactly 1 minute to shut down. (This might be a bug
related to autovacuum_naptime.)
Now you can access gitweb at http://yourserver/gitweb by simply adding
this to configuration.nix (assuming services.lighttpd.enable = true);
services.lighttpd.gitweb.enable = true;
The path to all bare repositories served by gitweb can be set with this
option (default value below):
services.lighttpd.gitweb.projectroot = "/srv/git";

Instead of forcing users to configure lighttpd manually, make it an
option. The current services.lighttpd.configText option can still be
used for manual configuration, but if it is left blank (default) we'll
use the new generated config file.
The generated config file ensures that the server drops root priveleges
and runs as the "lighttpd" user. It pulls in some new config params that
can be set in configuration.nix (here with default values):
services.lighttpd.document-root = "/srv/www"
services.lighttpd.port = 80
services.lighttpd.extraConfig = "" # appended to the generated file
And it enables access and error logging to the systemd journal.

After Linux 3.2(?), /proc/bus/usb (and usbfs (or usbdevfs?)) went away,
leaving virtualbox no way to determine what USB devices were connected
to the system. The solution was to add some virtualbox specific udev
rules to populate /dev/vboxusb with what was in /proc/bus/usb before.

Activation scripts are run before systemd is started, so unless users
are loading firmware in the initrd (which AFAICT we currently have no
support for) the previous /sys-based setting of firmware_class was
ineffective on boot.

Setting $TZDIR to ${pkgs.tzdata}/share/zoneinfo can cause logged-in
sessions to refer to a garbage-collected zoneinfo directory. So use
/etc/zoneinfo instead.
We don't need to set $TZ, because we have /etc/localtime. In fact,
setting $TZ without $TZDIR doesn't work anymore since Glibc no longer
contains zone info.
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.
