Grub uses mdadm to find out the device it is on, especially when mdadm itself
resides in a separate boot partition. When bootstrapping from a NixOS
installation CD, it's not a big issue because usually the paths from the Nix
store of the installation CD are matching with the ones in the chrooted
environment.

This allows to add additional raw disk images to the VM, which therein are
available as /dev/vdb, /dev/vdc, /dev/vde and so on. Especially when testing
partitioning, this could be useful.

This works around a bug in infinality that causes broken rendering in
some cases. Issue NixOS/nixpkgs#663.
Upstream suggests that "slight" is a better/safer default in any case.
It also looks better, IMHO, YMMV.
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.
```

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.
