even if cups rewrites its config file due to config changes made through
its web-based management UI, we need to keep the PATH pointing to
currently-live nix store directories. fixes #20806.
Need to pass `cups.out` to `systemd.packages`, lest we end up with an invalid
generated unit containing only directives set in the service module.
This patch gives us a valid cups.service unit but, vexingly, does not fix the
test failure at NixOS/nixpkgs#14748
And set the default value to "Address @LOCAL". This change is needed to
find printers at my workplace (with "lpinfo -v" or the
"system-config-printer" GUI). Ubuntu 14.04 also has this as default.
snmp.conf does not seem to be needed in restartTriggers, because it is
not the cups daemon itself that reads it, but some helper programs that
it spawns on demand.
This gets rid of
systemd[1]: Cannot add dependency job for unit avahi-daemon.service, ignoring: Unit avahi-daemon.service failed to load: No such file or directory.
There currently are collisions between the main CUPS package and the
filters package, which are:
* $storepath/share/cups/banners/classified
* $storepath/share/cups/banners/confidential
* $storepath/share/cups/banners/secret
* $storepath/share/cups/banners/standard
* $storepath/share/cups/banners/topsecret
* $storepath/share/cups/banners/unclassified
* $storepath/share/cups/data/testprint
And they actually have different content, so let's ignore those for now
until we have a better fix.

Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.
If you want CUPS to receive UDP printer announcements from the rest of the
world, please add
networking.firewall.allowedUDPPorts = [ 631 ];
to /etc/nixos/configuration.nix.
See <http://lists.science.uu.nl/pipermail/nix-dev/2013-November/011997.html>
for the discussion that lead to this.
That is, you can say
security.pam.services.sshd = { options... };
instead of
security.pam.services = [ { name = "sshd"; options... } ];
making it easier to override PAM settings from other modules.
