This reverts commit ab6c8643d4. Issue
https://github.com/NixOS/nix/issues/609 has been resolved, the new Nix
version is available after 86eaeb4c0a, and
using nix-collect-garbage has the advantage that the '-d' flag is
available, which nix-store doesn't have.
Or else users may see this unfriendly message:
error: cannot coerce null to a string, at .../nixos/modules/services/x11/display-managers/gdm.nix:107:49
Changes the option and explicitely sets it for each desktopManager.
Reasoning: Currently,
services.xserver.displayManager.desktopManagerHandlesLidAndPower is set
to true by default. This creates a problem for users without desktop
environments activated, since lid management simply doesn't work
(and they have to be lucky to find this option).

This reverts commit a8eb2a6a81. OpenSSH
7.0 is causing too many interoperability problems so soon before the
15.08 release.
For instance, it causes NixOps EC2 initial deployments to fail with
"REMOTE HOST IDENTIFICATION HAS CHANGED". This is because the client
knows the server's ssh-dss host key, but this key is no longer
accepted by default. Setting "HostKeyAlgorithms" to "+ssh-dss" does
not work because it causes ssh-dss to be ordered after
"ecdsa-sha2-nistp521", which the server also offers. (Normally, ssh
prioritizes host key algorithms for which the client has a known host
key, but not if you set HostKeyAlgorithms.)
Now it generates notifications for auto-detected devices as well as
for explicitly configured ones, sends well formed e-mails and supports
immediate `wall` and `xmessage` notifications.
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 provides support for Ubuntu Fan Networking [1].
This includes:
* The fanctl package, and a corresponding NixOS service.
* iproute patches.
* kernel patches.
