Add a cage module to nixos. This can be used to make kiosk-style
systems that boot directly to a single application. The user (demo by
default) is automatically logged in by this service and the
program (xterm by default) is automatically started.
This is useful for some embedded, single-user systems where we want
automatic booting. To keep the system secure, the user should have
limited privileges.
Based on the service provided in the Cage wiki here:

* prometheus-nginx-exporter: 0.5.0 -> 0.6.0
* nixos/prometheus-nginx-exporter: update for 0.6.0
Added new option constLabels and updated virtualHost name in the
exporter's test.
Prior to this fix, changes to certain settings would not be applied
automatically and users would have to know to manually restart the
affected service. A prime example of this is
`services.mailman.hyperkitty.baseUrl`, or various things that affect
`mailman3/settings.py`
The current weekly setting causes every NixOS server to try to renew
its certificate at midnight on the dot on Monday. This contributes to
the general problem of periodic load spikes for Let's Encrypt; NixOS
is probably not a major contributor to that problem, but we can lead by
example by picking good defaults here.
The values here were chosen after consulting with @yuriks, an SRE at
Let's Encrypt:
* Randomize the time certificates are renewed within a 24 hour period.
* Check for renewal every 24 hours, to ensure the certificate is always
renewed before an expiry notice is sent out.
* Increase the AccuracySec (thus lowering the accuracy(!)), so that
systemd can coalesce the renewal with other timers being run.
(You might be worried that this would defeat the purpose of the time
skewing, but systemd is documented as avoiding this by picking a
random time.)
The environment.systemPackages option lacks in the example which is used in the next paragraph to explain merging of the options defined by multiple modules.
This is useful when buildLayeredImage is called in a generic way
that should allow simple (base) images to be built, which may not
reference any store paths.
The current behavior lets `system` default to
`builtins.currentSystem`. The system value specified to
`eval-config.nix` has very low precedence, so this should compose
properly.
Fixes#80806
I am not sure how this ever passed on hydra but 30s is barely enough to
pass the configure phase of opensmtpd. It is likely the package was
built as part of another jobset. Whenever it is built as part of the
test execution the timeout propagates and 30s is clearly not enough for
that.
On servers especially, phantomjs2 pulls graphical dependencies which is unecessary.
This pathes enable the package to be linked/installed without
phantomjs2. Phantomjs2 is disabled by default since it has been deprecated in grafana https://grafana.com/docs/grafana/latest/guides/whats-new-in-v6-4/
The subtest was mainly written to demonstrate the VRF-issues with a
5.x-kernel. However this breaks the entire test now as we have 5.4 as
default kernel. Disabling the test for now, I still need to find some
time to investigate.
Directory mode 755 is standard for running services. Without this,
downloadDirPermissions doesn't have any use since other users can't even
look inside the main transmission directory
* nixos/gdm: Fix pulseaudio tmpfiles structure
Fix the following startup failure of the sound service in the gdm
session that was introduced by #75893:
```

Note we're not using wayland default in the graphical media because it
could cause headaches for Nvidia users. But the session is still available
if someone logs out.
lego already bundles the chain with the certificate,[1] so the current
code, designed for simp_le, was resulting in duplicate certificate
chains, manifesting as "Chain issues: Incorrect order, Extra certs" on
the Qualys SSL Server Test.
cert.pem stays around as a symlink for backwards compatibility.
[1] 5cdc0002e9/acme/api/certificate.go (L40-L44)
It was added in PR #79786 (7a625e7) and then removed in commit 2de3caf
(apparently unintentionally as a rebase conflict).
_I think the ordering used by Eelco would sort the line this way._
This reverts commit 6a756af3e7.
Currently zshenv by default only set fpath and HELPDIR without exporting them.
A parent shell would also not set those variables usually as they are shell local.
It also sources a file called set-environment but this is protected by an
environment variable called __NIXOS_SET_ENVIRONMENT_DONE. Hence any modification
done by the parent shell should persist as long as __NIXOS_SET_ENVIRONMENT_DONE
is not unset.
This behavior deviates from what we do in bashrc and breaks common setups such
as tmux/mosh or screen.
Fixes#80437
This commit fixes#76620. It moves ExecStartPre and ExecStopPost to
preStart and postStop, as these options are composable. It thus allows
adding additional initialisation scripts or cleanup scripts to the systemd
unit of the docker container.
This leads to inconsistent results between local builds and
Hydra. Also Nix is not a general purpose language, we shouldn't be
parsing .git from inside Nix code.
In 0945178b3c we decided that Perl-based
VM tests should be deprecated and will be removed between 20.03 and
20.09. So let's switch `nixos-build-vms(8)` to python as well (which is
entirely interactive, so other scripts won't break).
In my experience, the test-driver isn't used most of the time, so this
patch is mainly supposed to get rid of the (probably misleading)
deprecation warning when running `nixos-build-vms`. Apart from that, the
interface for python's test-driver is way nicer.
This option allows the user to control whether or not the docker container is
automatically started on boot. The previous default behavior (true) is preserved
* nixos/postgresql: support 0750 for data directory
This is rework of part of https://github.com/NixOS/nixpkgs/pull/46670.
My usecase was to be able to inspect PG datadir as wheel user.
PG11 now allows starting server with 0750 mask for data dir.
`groupAccess = true` now does this automatically. The only thing you have to do
is to set group ownership.
For PG10 and below, I've described a hack how this can be done. Before this PR
hack was impossible. The hack isn't ideal, because there is short
period of time when dir mode is 0700, so I didn't want to make it official.
Test/example is present too.
* postgresql: allow changing initidb arguments via module system
Closes https://github.com/NixOS/nixpkgs/issues/18829
+ some cleanups
* addressed review comments and some fixes
* whoops
* change groupAccess to tristate, to not force `chmod` on dataDir.
Making mask either 0700 or 0750 is too restrictive..
* WIP
* let's not support group mode for versions pre-11.
The only fix is to change mode to 0700 before start, because otherwise postgresql
doesn't start, and error is non-obvious.
