androidenv did not previously write license files, which caused certain
gradle-based Android tools to fail. Restructure androidenv's list of
Android packages into a single repo.json file to prevent duplication
and enable us to extract the EULA texts, which we then hash with
builtins.hashString to produce the license files that Android gradle
tools look for.
Remove includeDocs and lldbVersions, as these have been removed
from the Android package repositories.
Improve documentation and examples.
* Content of `programlisting` shouldn't be indented, otherwise it's
weirdly indented in the output.
* Use `<xref linkend=.../>` in the release notes: then users can
directly go to the option documentation when reading release notes.
* Don't use docbook tags in `mkRemovedOptionModule`: it's only used
during evaluation where docbook isn't rendered.
Previously, after the version bump to v247, we broke journalctl --grep
as libpcre2 was lazily loaded during runtime using dlopen(3). This
ensures that we have a test case that alerts us when it fails again.
As per the in-line comment, this is where distros should configure it.
Not via kernel command line parameters.
As found by looking at the implementation, while exploring the cause of
a bug on the Raspberry Pi 4, it was found that `cma=` on the command
line parameters will overwrite the values a device tree will have
configured for a given platform.
With this, the more recent 5.4 vendor kernel boots just fine on the
Raspberry Pi 4 using our common configuration.
This includes setting up everything for the mainline Raspberry Pi 4
image.
In fact, the only difference left in the Raspberry Pi 4-specific image
is the kernel from the vendor.
This reverts commit f19b7b03a0, reversing
changes made to 572a864d02.
Sorry. I pushed the wrong staging-next (the one that had my master
merged in). This was not intended.
Services that have dynamic users require nscd to resolve users
via pam_systemd. Those services might not even create
their own dynamic users itself i.e. iptables.
To make sure nscd is always started when this is happening we move
nscd to sysinit.target and make sure that it is always started before
starting/reloading/restarting any other service.
There are two use case for this flag:
1. NixOS developer usually use a nixpkgs checkout for development.
Copying nixpkgs everytime when rebuilding NixOS is way to slow, even
with NVME disks.
2. Folks migrating from impure configuration in a sufficient complex
infrastructure need this flag to gradually migrate to NixOS flakes.
Instead of treating the sddm config a wall of text that doesn't allow us
to override anything, turn it into an attribute set.
We dump `extraConfig` and instead introduce `settings` that is merged
with the module defaults to provide the final configuration.
There is some additional noise in here due to nixpkgs-fmt.
* nixos/xmonad: xmonad config w/ghc+xmessage
When the "config" option isn't set, we use xmonad-with-packages to
provide xmonad with runtime access to an isolated ghc, ensuring it can
recompile and exec a user's local config (e.g. $HOME/.xmonad/xmonad.hs)
regardless of which ghc (if any) is on PATH.
When the "config" option is set, however, we compile a configured xmonad
executable upfront (during nixos-rebuild), and prior to this commit, it
was not provided with runtime access to an isolated ghc.
As a result, with the "config" option set, it was not possible
to recompile and exec a user's local config unless there was a
compatible version of ghc on PATH with the necessary packages (xmonad,
xmonad-contrib, etc.) in its package database. Adding such a ghc to
environment.systemPackages, e.g.
(haskellPackages.ghcWithPackages (ps: with ps; [xmonad xmonad-contrib]))
is problematic because it adds both ghc and an unconfigured xmonad to
PATH, e.g.
$ ls -l $(which xmonad ghc)
lrwxrwxrwx ... /run/current-system/sw/bin/ghc -> /nix/store/...-ghc-8.10.2-with-packages/bin/ghc
lrwxrwxrwx ... /run/current-system/sw/bin/xmonad -> /nix/store/...-ghc-8.10.2-with-packages/bin/xmonad
Having the unconfigured xmonad on PATH is particularly bad because
restarting xmonad will dump the user into the unconfigured version, and
if no local config exists (e.g. in $HOME/.xmonad/xmonad.hs), they'll be
left in this unconfigured state.
In this commmit, we give the configured xmonad runtime access to ghc
like xmonad-with-packages does for the unconfigured version. The aim
is to allow the user to switch between the nixos module's config and a
local config (e.g. $HOME/.xmonad/xmonad.hs) at will, so they can try out
config changes without performing a nixos-rebuild.
Since the xmonad on PATH is the configured executable, there's no
danger a user could unwittingly restart into the unconfigured version,
and because xmonad will refuse to recompile when no local config
exists, there's no danger a user could unwittingly recompile into an
unconfigured version.
Given that a local config exists, the recompile/restart behavior depends
on two factors:
- which entry point is used
* 'XMonad.xmonad' (default)
* 'XMonad.launch' (recommended in "config" option description)
- what operation is triggered (i.e. via mod+q)
* `spawn "xmonad --recompile && xmonad --restart"` (default)
* `restart "xmonad" True`
* custom function
If the default 'XMonad.xmonad' entrypoint and default mod+q operation
are used, hitting mod+q will compile and exec the local config, which
will remain in use until next time the display manager is restarted.
If the entrypoint is changed to 'XMonad.launch' but mod+q left with its
default operation, hitting mod+q will have no visible effect. The logs
(as seen by running `journalctl --identifier xmonad --follow`) will show
an error,
X Error of failed request: BadAccess (attempt to access private resource denied)
which indicates that the shell was unable to start xmonad because
another window manager is already running (namely, the nixos-configured
xmonad).
https://wiki.haskell.org/Xmonad/Frequently_asked_questions#X_Error_of_failed_request:_BadAccess_.28attempt_to_access_private_resource_denied.29
Changing the mod+q operation to `restart "xmonad" True` (as recommended
in the "config" option's description) will allow a restart of the
nixos-configured xmonad to be triggeredy by hitting mod+q.
Finally, if the entrypoint is 'XMonad.launch', mod+q has been
bound to `restart "xmonad" True` and another key bound to a custom
recompile/restart function (e.g. `compileRestart` as shown in the
"config" option example), the user can switch between the nixos module's
config and their local config, with the custom key switching to the
local config and mod+q switching back.
* nixos/xmonad: refactor let binding
* nixos/xmonad: refactor (eliminate duplicate code)
* nixos/xmonad: install man pages
Prior to this commit, man pages were not installed if the "config"
option was set.
* nixos/xmonad: comment grammar fixups
* nixos/xmonad: writeStateToFile in example config
Calling writeStateToFile prior to recompiling and restarting allows
state (workspaces, etc.) to be preserved across the restart.
* nixos/xmonad: add ivanbrennan to maintainers
* nixos/xmonad: adjust compileRestart example
* nixos/xmonad: add missing import to example config
@poettering decided we only need a limited number of inodes in our /tmp,
so why not limit that for every systemd user? That makes medium-sized nix
builds impossible so this commit restores the old behaviour which is the
kernel default of half the number of physical RAM pages which does not
seem too unreasonable to me.
Since version 5.2.0 there's non-empty stop phase:
ExecStopPost=/usr/bin/env rm -f "/run/knot-resolver/control/%i"
but it's perfectly OK to run that from a different version
(and typically it's no-op anyway). Real-life example where this helps:
https://github.com/NixOS/nixpkgs/issues/49528#issuecomment-747723198
This allows to use files containing only the mpd password without the
permissions, making it easier for other programs connecting to mpd to read the
password from the same password file.

This reverts commit 20257280d9, reversing
changes made to 926a1b2094.
It broke nixosTests.installer.simpleUefiSystemdBoot
and right now channel is lagging behing for two weeks.
This reverts commit 8f177612b1.
Attempting to start any service from udev when systemd-udev-settle is
used at all hangs the boot for 2min. See issue #107341.
Prior to this commit, installation over serial console would requiring
manually having to modify the kernel modeline, as described in
https://github.com/NixOS/nixpkgs/issues/58198 .
This is unnecessarily fiddly, so this commit adds a syslinux boot
entry that has serial enabled.
GRUB already has a serial console entry:
2c07a0800a/nixos/modules/installer/cd-dvd/iso-image.nix (L311-L317)
Why 115200 bps? This is already used in other places, e.g. https://github.com/NixOS/nixpkgs/pull/58196
I tested this change by building the image, booting the image, and
observing the boot process over serial:
$ cd nixos/
$ nix-build -A config.system.build.isoImage -I nixos-config=modules/installer/cd-dvd/installation-cd-minimal.nix default.nix
$ sudo cp /nix/store/arcl702c3z8xlndlvnfplq9yhixjvs9k-nixos-20.09pre-git-x86_64-linux.iso/iso/nixos-20.09pre-git-x86_64-linux.iso /dev/sdb

Fixes https://github.com/NixOS/nixpkgs/issues/107255
Fixes that `containers.<name>.extraVeths.<name>` configuration was not
always applied.
When configuring `containers.<name>.extraVeths.<name>` and not
configuring one of `containers.<name>.localAddress`, `.localAddress6`,
`.hostAddress`, `.hostAddress6` or `.hostBridge` the veth was created,
but otherwise no configuration (i.e. no ip) was applied.
nixos-container always configures the primary veth (when `.localAddress`
or `.hostAddress` is set) to be the containers default gateway, so
this fix is required to create a veth in containers that use a different
default gateway.
To test this patch configure the following container and check if the
addresses are applied:
```
containers.testveth = {
extraVeths.testveth = {
hostAddress = "192.168.13.2";
localAddress = "192.168.13.1";
};
config = {...}:{};
};
```
This means that all systems running from master will trigger
new certificate creation on next rebuild. Race conditions around
multiple account creation are fixed in #106857, not this commit.
Previously the .enable option was used to encode the condition as well,
which lead to some oddness:
- In order to encode an assertion, one had to invert it
- To disable a check, one had to mkForce it
By introducing a separate .check option this is solved because:
- It can be used to encode assertions
- Disabling is done separately with .enable option, whose default can be
overridden without a mkForce
Since slurm-20.11.0.1 the dbd server requires slurmdbd.conf to be
in mode 600 to protect the database password. This change creates
slurmdbd.conf on-the-fly at service startup and thus avoids that
the database password ends up in the nix store.
