* Patched fish to load /etc/fish/config.fish if it exists (by default,
it only loads config relative to itself)
* Added fish-foreign-env package to parse the system environment
closes#5331
The idea that the interactive bash prompt isn't set in case of TERM=dumb
is intended to fix problems when other machines log remotely into a
NixOS installation via Tramp. A side-effect that change was, however,
that Emacs' shell-mode no longer had a correct prompt. I suppose the
presence of
INSIDE_EMACS=24.5.2,comint
is a sufficiently unique indication that the current interactive shell
is running inside of an Emacs and that the prompt can thus be configured
safely.
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.)
`man 1 info` says:
The first non-option argument, if present, is the menu entry to
start from; it is searched for in all `dir' files along INFOPATH.
If it is not present, info merges all `dir' files and shows the
result. Any remaining arguments are treated as the names of menu
items relative to the initial node visited.
Which means that this does what previous programs/info did and #8519
(on-the-fly infodir generation for Emacs) wanted to do, but for both
programs.
In 14f09e0, I've introduced the module under modules/programs, because
the legacy virtualbox.nix was also under that path. But because we
already have modules/virtualisation/virtualbox-guest.nix, it really
makes sense to put this module alongside of it as well.
This module thus has no change in functionality and I've tested
evaluation against nixos/tests/virtualbox.nix and the manual.

My original reason to put it at the beginning of NIX_PATH was to allow
shipping a particular version <nixpkgs> with a channel. But in order to
do that, we can still let the channel expression ship with a custom
version of nixpkgs by something like <channel/nixpkgs> and the builder
of the channel could also rewrite self-references.
So the inconvenience is now shifted towards the maintainer of the
channel rather than the user (which isn't nice, but better err on the
side of the developer rather than on the user), because as @edolstra
pointed out: Having the channels of root at the beginning of NIX_PATH
could have unintended side-effects if there a channel called nixpkgs.

This is very useful if you want to distribute channels (and thus
expressions as well) in a similar fashion to Debians APT sources (or
PPAs or whatnot).
So, for example if you have a channel with some additional functions
or packages, you simply add that channel with:
sudo nix-channel --add https://example.com/my-nifty-channel foo
And you can access that channel using <foo>, for example in your
configuration.nix:
{
imports = [ <foo/modules/shiny-little-module> ];
environment.systemPackages = with import <foo/pkgs> {}; [ bar blah ];
services.udev.extraRules = import <foo/lib/udev/mkrule.nix> {
kernel = "eth*";
attr.address = "00:1D:60:B9:6D:4F";
name = "my_fast_network_card";
};
}
Within nixpkgs, we shouldn't have <nixos> used anywhere anymore, so we
shouldn't get into conflicts.

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.
