Useful for installing NixOS in place on another distro. For instance:
$ nix-env -iE '_: with import <nixpkgs/nixos> { configuration = {}; }; with config.system.build; [ nixos-generate-config manual.manpages ]'
$ sudo mkdir /etc/nixos
$ sudo `which nixos-generate-config`
… edit the configuration files in /etc/nixos using man configuration.nix
if needed
maybe add: users.extraUsers.root.initialHashedPassword = "" ?
… Build the entire NixOS system and link it to the system profile:
$ nix-env -p /nix/var/nix/profiles/system -f '<nixpkgs/nixos>' -A system --set
… If you were using a single user install:
$ sudo chown -R 0.0 /nix
… NixOS is about to take over
$ sudo touch /etc/NIXOS
$ sudo touch /etc/NIXOS_LUSTRATE
… Let's keep the configuration files we just created
$ echo etc/nixos | sudo tee -a /etc/NIXOS_LUSTRATE
$ sudo mv -v /boot /boot.bak &&
sudo /nix/var/nix/profiles/system/bin/switch-to-configuration boot
$ sudo reboot
… NixOS boots, Stage 1 moves all the old distro stuff in /old-root.

Test plan:
* Check that `fonts.fontconfig.ultimate.preset` changes things;
* Check that `fonts.fontconfig.dpi` changes things;
* Check that `fonts.fontconfig.defaultFonts.monospace` changes things;
Tested with AbiWord, mousepad and Firefox.
The fontconfig-ultimate patches are unmaintained. Since they were
not updated for newer FreeType versions, this removes them and
disables fontconfig-ultimate by default.
This removes our hardcoded presets which weren't updated for quite some time.
Infinality now has new hardcoded presets in freetype, which can be overriden if
desired with environment variables (as before). Accordingly, updated NixOS
module to set the hardcoded preset.
Additionally used a more "right" type for substitutions.
Before commit 54fa0cfe4e, the `redshift`
service was run with the environment variable `DISPLAY` set to `:0`.
Commit 54fa0cfe4e changed this to
instead use the value of the `services.xserver.display` configuration
option in the value of the `DISPLAY` variable. In so doing, no default
value was provided for the case where `services.xserver.display` is
`null`.
While the default value of `services.xserver.display` is `0`, use of
which by the `redshift` module would result in `DISPLAY` again being
set to `:0`, `services.xserver.display` may also be `null`, to which
value it is set by, e.g., the `lightdm` module.
In the case that `services.xserver.display` is `null`, with the change
made in commit 54fa0cfe4e, the `DISPLAY`
variable in the environment of the `redshift` service would be set to
`:` (a single colon), which, according to my personal experience,
would result in —
- the `redshift` service failing to start; and
- systemd repeatedly attempting to restart the `redshift` service,
looping indefinitely, while the hapless `redshift` spews error
messages into the journal.
It can be observed that the malformed value of `DISPLAY` is likely at
fault for this issue by executing the following commands in an
ordinary shell, with a suitable `redshift` executable, and the X11
display not already tinted:
- `redshift -O 2500` — This command should reduce the color
temperature of the display (making it more reddish).
- `DISPLAY=':' redshift -O 6500` — This command should raise the
color temperature back up, were it not for the `DISPLAY`
environment variable being set to `:` for it, which should cause
it to, instead, fail with several error messages.
This commit attempts to fix this issue by having the `DISPLAY`
environment variable for the `redshift` service default to its old
value of `:0` in the case that `services.xserver.display` is `null`.
I have tested this solution on NixOS, albeit without the benefit of a
system with multiple displays.
gdnc is a user process and can't be made into a NixOS module very
easily. It can still be put in the user's login script. According to the
GNUstep documentation it will be started as soon as it is needed.
- Replace hand-rolled version of nixos-install in make-disk-image by an
actual call to nixos-install
- Required a few cleanups of nixos-install
- nixos-install invokes an activation script which the hand-rolled version
in make-disk-image did not do. We remove /etc/machine-id as that's
a host-specific, impure, output of the activation script
Testing:
nix-build '<nixpkgs/nixos/release.nix>' -A tests.installer.simple passes
Also tried generating an image with:
nix-build -E 'let
pkgs = import <nixpkgs> {};
lib = pkgs.lib;
nixos = import <nixpkgs/nixos> {
configuration = {
fileSystems."/".device = "/dev/disk/by-label/nixos";
boot.loader.grub.devices = [ "/dev/sda" ];
boot.loader.grub.extraEntries = '"''"'
menuentry "Ubuntu" {
insmod ext2
search --set=root --label ubuntu
configfile /boot/grub/grub.cfg
}
'"''"';
};
};
in import <nixpkgs/nixos/lib/make-disk-image.nix> {
inherit pkgs lib;
config = nixos.config;
diskSize = 2000;
partitioned = false;
installBootLoader = false;
}'
Then installed the image:
$ sudo df if=./result/nixos.img of=/dev/sdaX bs=1M
$ sudo resize2fs /dev/disk/by-label/nixos
$ sudo mount /dev/disk/by-label/nixos /mnt
$ sudo mount --rbind /proc /mnt/proc
$ sudo mount --rbind /dev /mnt/dev
$ sudo chroot /mnt /nix/var/nix/profiles/system/bin/switch-to-configuration boot
[ … optionally do something about passwords … ]
and successfully rebooted to that image.
Was doing all this from inside a Ubuntu VM with a single user nix install.
- Fix --no-bootloader which didn't do what it advertised
- Hardcode nixbld GID so that systems which do not have a nixbld user
can still run nixos-install (only with --closure since they can't
build anything)
- Cleanup: get rid of NIX_CONF_DIR(=/tmp)/nix.conf and pass arguments instead
- Cleanup: don't assume that the target system has '<nixpkgs/nixos>' or
'<nixos-config>' to see if config.users.mutableUsers. Instead check if
/var/setuid-wrappers/passwd is there
Installing NixOS now works from a Ubuntu host (using --closure).
nix-build -A tests.installer.simple '<nixpkgs/nixos/release.nix>' succeeds ✓
While useless, some builds may dabble with setuid bits (e.g.,
util-linux), which breaks under grsec. In the interest of user
friendliness, we once again compromise by disabling an otherwise useful
feature ...

It uses import-from-derivation, which is a bad thing, because this
causes hydra-evaluator to build Cassandra at evaluation time.
$ nix-instantiate nixos/release.nix -A tests.cassandra.i686-linux --dry-run

Also, the module is a mess (bad option descriptions, poor indentation,
a gazillion options where a generic "config" option would suffice, it
opens ports in the firewall, it sets vm.swappiness, ...).
- Agent now takes a full URL to the Go.CD server

Addresses #17218 in a better way in that it doesn't create a
".git-revision" file on every nixos-rebuild, because we already have
".git" available. Even if we don't nixos-rebuild can't create the
"git-revision" file.
Tested via:
nix-build -E '(import ./nixos/tests/make-test.nix {
name = "foo";
machine = {};
testScript = "startAll; $machine->execute(\"nixos-version >&2\");";
})'
Closes: #17610

Let's first try if we can determine the Git revision from the .git
directory and if that fails, fall back to get the info from the
".git-revision" file... and after that use something generic like
"master".
This should address #17218 in better way, because we don't need to
create another redundant file in the source checkout of nixpkgs.
I'm not going to route of falling back to using .git, because after
55d881e, we already have ".git-revision" files in people's Git
repositories, which in turn means that nixos-version will report that
old file every time even if the working tree has updated.

This reverts commit 1e534e234b.
We already should have a .git directory if it is managed via Git,
otherwise there is no way to get the Git revision if neither
.git-revision or .git is present.
But having .git-revision _and_ .git present seems very much redundant to
me.

The builder has this convoluted `while` loop which just replicates
`readlink -e`. I'm sure there was a reason at one point, because the
loop has been there since time immemorial. It kept getting copied
around, I suspect because nobody bothered to understand what it actually
did.
Incidentally, this fixes#17513, but I have no idea why.
From @fpletz: Keep poolConfigs option for backwards-compatibility.
The original commit 6b3f5b5a42 was previously
reverted by c7860cae1a but the issues were
resolved.
Closes#17460
Changed the wrapper derivation to produce a second output containing the sandbox.
Add a launch wrapper to try and locate the sandbox (either in /var/setuid-wrappers or in /nix/store).
This launch wrapper also sheds libredirect.so from LD_PRELOAD as Chromium does not tolerate it.
Does not trigger a Chromium rebuild.

The varnish tools (varnishstat, varnishlog, ...) tried to load the VSM
file from a spurious var directory in the Nix store. Fix the default so
the tools "just work" when also keeping services.varnish.stateDir at the
default.
Notes:
- The tools use $localstatedir/$HOSTNAME so I've adapted the default for
stateDir as well to contain hostName.
- Added postStop action to remove the localstatedir. There is no point
in keeping it around when varnish does not run, as it regenerates it
on startup anyway.
Fixes#7495
The name gitlab-runner clashes with a component of Gitlab CI with the
same name and only confuses people. It's now called gitlab-bundle and
a convenience-script gitlab-rake for easier invocation of rake tasks
was added. This was the primary use case of gitlab-runner.
The module will configure a Cassandra server with common options being
tweakable. Included is also a test which will spin up 3 nodes and
verify that the cluster can be formed, broken, and repaired.
In light of Emacs packaging improvements such as those mentioned
in #11503, and with the addition of a systemd service (#15807
and #16356), and considering that the wiki page is completely
out of date (#13217), it seems that some documentation is in order.
Enabling EFI runtime services provides a venue for injecting code into
the kernel.
When grsecurity is enabled, we close this by default by disabling access
to EFI runtime services. The upshot of this is that
/sys/firmware/efi/efivars will be unavailable by default (and attempts
to mount it will fail).
This is not strictly a grsecurity related option, it could be made into
a general option, but it seems to be of particular interest to
grsecurity users (for non-grsecurity users, there are other, more
immediate kernel injection attack dangers to contend with anyway).
* Hydra doesn't like spaces in filenames.
* The zip file contained nix/store/.../OEBPS rather than OEBPS at
top-level, causing some programs (like okular) to barf.
* Remove the redundant $dst/epub directory.
Adds a new chain in the raw table for reverse path filtering and optional
logging. A rule to allow serving DHCPv4 was also added as it is commonly
needed and poses no security risk even when no DHCPv4 server is running.
Fixes#10101.
Adds options for tcp streaming and avahi zeroconf support (so that the
server can be easily found by clients).
There is also an option to allow anonymous clients to stream to the
server (by default pulseaudio uses a cookie mechanism, see manpage).
Instead of one package `extra-cmake-modules`, there is now `ecm` and
`ecmNoHooks`. The latter is used when one does not want to incur a Qt 5
dependency; it is also available as a top-level package
`extra-cmake-modules`.
With these changes, a container can have more then one veth-pair. This allows for example to have LAN and DMZ as bridges on the host and add dedicated containers for proxies, ipv4-firewall and ipv6-firewall. Or to have a bridge for normal WAN, one bridge for administration and one bridge for customer-internal communication. So that web-server containers can be reached from outside per http, from the management via ssh and can talk to their database via the customer network.
The scripts to set up the containers are now rendered several times instead of just one template. The scripts now contain per-container code to configure the extra veth interfaces. The default template without support for extra-veths is still rendered for the imperative containers.
Also a test is there to see if extra veths can be placed into host-bridges or can be reached via routing.
This makes the container a bit more secure, by preventing root
creating device nodes to access the host file system, for
instance. (Reference: systemd-nspawn@.service in systemd.)
Revert httpConfig its old behaviour and make it mutually exclusive to
the new structured configuration. Adds appendHttpConfig to have the
ability to write custom config in the generated http block.
This reverts commit 6b3f5b5a42 because it
introduced a non-backwards compatible change in the phpfpm interface,
without really needing to. The new interface, if needed, can be re-added
alongside the old interface.
Commit 98e419c0e2 ("tt-rss service: init at 16.3")
depends on the new interface, so this commit updates the tt-rss service
to work with the old services.phpfpm.poolConfigs interface.
Update gocd-server package version to 16.6.0-3590 including new sha. Modify heapSize
and maxMemory mkOption to accurately reflect their intended purpose of configuring
initial java heap sizes.
Note: the option to configure the watchdog timeout seems to be gone
in the 2.3 series of Logstash. It complains about an unknown option
and it is not in the source anymore. I am thus removing this
configuration option to adjust the service to these changes, too.
This patch adds handling of a directory becoming a symlink in
/etc. Before this patch, the directory wasn't removed and then
symlinking failed, which caused directory not being updated at all.
The idea for the patch goes to @abbradar at

The only difference here -- it will not replace user configs.
