It seems like there's an upstream bug in the "lpstat" command. We need
to specify the server's port.

This reverts commit d170c98d13.
niksnut argues that we need smaller system closures, not bigger.
So users facing the trouble of getting gcc rebuilds after nix-collect-garbage
for any minimal nixos configuration change should use other means of
not losing the stdenv output.
One way is to keep one somewhere: nix-build -A stdenv -o stdenv '<nixpkgs>'.
Another may be to use nix.conf options like gc-keep-outputs, gc-keep-derivations
or env-keep-derivations.
This will help a lot on ARM, where nix-collect-garbage erases gcc; then, any
change to a small system config file requires rebuilding gcc again.
I don't know why it does not happen on x86. Maybe it just pulls the gcc from
hydra, if garbage is collected.
It boots, but some things still don't work:
1) Installation of DTBs
2) Boot of initrd
Booting still needs a proper config.txt in /boot, which could probably be
managed by NixOS.
During the refactor of the networkd stuff in f8dbe5f, a lot of the
options are now needed by systemd.nix as well as networkd.nix but
weren't moved by that commit as well.
For now, this fixes all networkd VM tests except for the macvlan one and
thus it should fix#7505 for at least DHCP-based configuration.

In f8dbe5f, the default value for networking unit "enabled" option
suddenly flipped to false. I have no idea of whether this happened by
accident, but I'm setting it to true again, because it essentially
breaks systemd networking support and we have systemd.network.enable to
have a "turn the world off" switch.
And of course, because the mentioned commit obviously wasn't done with
even a run of the simplest run of one of the network VM tests, we now
get an evaluation error if we switch useNetworkd to true.
Fixes the core issue of #7505.

Passing the chroot flag to nixos-install without arguments should now give you a
Bash shell as intended rather than try an empty path.
This was masked by the user's shell (usually /bin/bash) being defaulted to by
chroot, and being found since their paths used NixOS conventions.
When bootstrapping from other distributions, nixos-install is unable to find
various tools in the chroot since their paths aren't aware of NixOS conventions.
This makes a small change to existing code by specifying nixpkgs/nixos instead
of just nixos when running nix-instantiate in the chroot. I haven't tested this
outside of bootstrapping, but the same specification is used elsewhere in the
code so I don't see why it wouldn't work.
These services don't create files on disk, let alone on a network
filesystem, so they don't really need a fixed uid. And this also gets
rid of a warning coming from <= 14.12 systems.
Otherwise, the enabled -> disabled transition won't be handled
correctly (switch-to-configuration currently assumes that if a unit is
running and exists, it should be restarted).
This avoids the following warning:
Apr 19 10:53:48 xen systemd[1]: [/nix/store/...-unit-ddclient.service/ddclient.service:19] Unknown lvalue 'type' in section 'Service'
As `Type=simple` is the default in systemd, the assignment to the
service type can be simply dropped.
Added support for managing Plex plugins via Nix. This is done via an
"extraPlugins" configuration option which takes a list of paths to
plugin bundles, which are then symlinked into Plex's plugin directory
when the service is started.
Specifically, this fixes dnsmasq, which failed with
Apr 16 19:00:30 mandark dnsmasq[23819]: dnsmasq: DBus error: Connection ":1.260" is not allowed to own the service "uk.org.thekelleys.dnsmasq" due to security policies in the configuration file

after being enabled, due to dbus not being reloaded.
Thanks to @domenkozar for implicitly reminding me that documentation is
probably our biggest issue. And I'm a dumbass for contributing to that
situation, so let's do better than that and document it.
The current changes are only preparation for a bigger change coming real
soon[TM] in Hydra and release-tools, so right now it's still a bit
tedious to create custom channels.

This option causes the specified user to be automatically logged in at
the virtual console.
While at it, refactor and make a helper function for building the getty
command line.
This partially reverts commit 3a4fd0bfc6.
Addresses another concern by @edolstra that users might not want to
update *all* channels. We're now reverting to the old behaviour but
after updating the "nixos" channel, we just check whether the channel
ships with a file called ".update-on-nixos-rebuild" and if it exists, we
update that channel as well.
Other channels than these are not touched anymore.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
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.

Should make it even easier to use custom channels, because whenever the
user does a "nixos-rebuild --upgrade", it will also upgrade possibly
used ("used" as in referenced in configuration.nix) channels besides
"nixos". And if you also ship a channel tied to a particular version of
nixpkgs or even remove the "nixos" channels, you won't run into
unexpected situations where the system is not updating your custom
channels.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
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.
