While systemd suggests using the pre-defined graphical-session user
target, I found that this interface is difficult to use. Additionally,
no other major distribution, even in their unstable versions, currently
use this mechanism.
The window or desktop manager is supposed to run in a systemd user service
which activates graphical-session.target and the user services that are
binding to this target. The issue is that we can't elegantly pass the
xsession environment to the window manager session, in particular
whereas the PassEnvironment option does work for DISPLAY, it for some
mysterious reason won't for PATH.
This commit implements a new graphical user target that works just like
default.target. Services which should be run in a graphical session just
need to declare wantedBy graphical.target. The graphical target will be
activated in the xsession before executing the window or display manager.
Fixes #17858.
SSH expects a new line at the end of known_hosts file.
Without a new line the next entry goes on the same line
as the last entry in known_hosts causing errors.
The configuration { services.openssh.enable = true;
services.openssh.forwardX11 = false; } caused
programs.ssh.setXAuthLocation to be set to false, which was not the
intent. The intent is that programs.ssh.setXAuthLocation should be
automatically enabled if needed or if xauth is already available.

Fixes #10039, at least most of it.
The `sane` case wasn't fixed, as it calls a *function* in pkgs to get
the default value.
If we limit SSH_ASKPASS to interactive shells, users are unable to trigger
the ssh-passphrase dialog from their desktop environment autostart scripts.
Usecase: I call ssh-add during my desktop environment autostart and want to have
the passphrase dialog immediately after startup.
For this to work, SSH_ASKPASS needs to be propagated properly on
non-interactive shells.
- add missing types in module definitions
- add missing 'defaultText' in module definitions
- wrap example with 'literalExample' where necessary in module definitions

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.)
By making askPassword an option, desktop environment modules can
override the default x11_ssh_askpassword with their own equivalent for
better integration. For example, KDE 5 uses plasma5.ksshaskpass instead.
This was lost back in
ffedee6ed5. Getting this to work is
slightly tricky because ssh-agent runs as a user unit, and so doesn't
know the user's $DISPLAY.
IMHO, having a short timeout (1h) defeats the point of using
ssh-agent, which is not to have to retype passphrases all the time. Of
course, users who want timeouts can set programs.ssh.agentTimeout.
This restores the 14.04 behaviour.
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...
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.
