nscd doesn't create any files outside of /run/nscd unless the nscd.conf
"persistent" option is used, which we don't do by default. Therefore it
doesn't matter what UID/GID we run this service as, so long as it isn't
shared with any other running processes.
/run/nscd does need to be owned by the same UID that the service is
running as, but systemd takes care of that for us thanks to the
RuntimeDirectory directive.
If someone wants to turn on the "persistent" option, they need to
manually configure users.users.nscd and systemd.tmpfiles.rules so that
/var/db/nscd is owned by the same user that nscd runs as.
In an all-defaults boot.isContainer configuration of NixOS, this removes
the only user which did not have a pre-assigned UID.
Previously this module created both /var/db/nscd and /run/nscd using
shell commands in a preStart script. Note that both of these paths are
hard-coded in the nscd source. (Well, the latter is actually
/var/run/nscd but /var/run is a symlink to /run so it works out the
same.)
/var/db/nscd is only used if the nscd.conf "persistent" option is turned
on for one or more databases, which it is not in our default config
file. I'm not even sure persistent mode can work under systemd, since
`nscd --shutdown` is not synchronous so systemd will always
unceremoniously kill nscd without reliably giving it time to mark the
databases as unused. Nonetheless, if someone wants to use that option,
they can ensure the directory exists using systemd.tmpfiles.rules.
systemd can create /run/nscd for us with the RuntimeDirectory directive,
with the added benefit of causing systemd to delete the directory on
service stop or restart. The default value of RuntimeDirectoryMode is
755, the same as the mode which this module was using before.
I don't think the `rm -f /run/nscd/nscd.pid` was necessary after NixOS
switched to systemd and used its PIDFile directive, because systemd
deletes the specified file after the service stops, and because the file
can't persist across reboots since /run is a tmpfs. Even if the file
still exists when nscd starts, it's only a problem if the pid it
contains has been reused by another process, which is unlikely. Anyway,
this change makes that deletion even less necessary, because now systemd
deletes the entire /run/nscd directory when the service stops.
This postStart step was introduced on 2014-04-24 with the comment that
"Nscd forks into the background before it's ready to accept
connections."
However, that was fixed upstream almost two months earlier, on
2014-03-03, with the comment that "This, along with setting the nscd
service type to forking in its systemd configuration file, allows
systemd to be certain that the nscd service is ready and is accepting
connections."
The fix was released several months later in glibc 2.20, which was
merged in NixOS sometime before 15.09, so it certainly should be safe to
remove this workaround by now.
Add an option to set the rc-manager parameter in NetworkManager.conf,
which controls how NetworkManager handles resolv.conf. This sets the
default rc-manager to "resolvconf", which solves #61490. It
additionally allows the user to change rc-manager without interference
from configuration activations.
This commit adds new options to the Deluge service:
- Allow configuration of the user/group which runs the deluged daemon.
- Allow configuration of the user/group which runs the deluge web
daemon.
- Allow opening firewall for the deluge web daemon.
This commit adds new configuration options to the Lidarr module that
allows configuration of the user and group that Lidarr runs as; and to
open the firewall for the Lidarr port.
This was added in #19936 so that vulkan-loader finds the ICD config files. It is
not needed any more after #62869 where it was ensured that the loader looks in
/run/opengl-driver(-32)/share.
There are many support questions when people add a new binary cache
and they suddenly lose nixos substitutions.
Most of the users want to keep that, so we're doing a breaking change.
Previously to disable all binary caches one had to do:
nix.binaryCache = [];
Now the same is possible via:
nix.binaryCache = lib.mkForce;
Applies OpenWRT's noscan patch to hostapd and the relevant option to
the hostapd module.
This noscan patch adds a new `noscan` option allowing us to create
some overlapping BSSs in HT40+/- mode.
Note: this option is disabled by default, we leave this up to the end
user whether it should be enabled or not.
Not being able to create those overlapping BSSs is basically
preventing us to use 802.11n in any urban area where chances to
overlap with another SSID are extremely high.
The patch we are using is a courtesy of the openwrt team and is
applied to the defaul hostapd package in both OpenWRT and Archlinux.
Using "builtins.currentSystem" doesn't work in pure evaluation mode,
and even when it's explicitly set (which it always is, in
nixos/lib/eval-config.nix), it breaks manual generation because the
manual tries to render the default value.
The change to "NixOS Test Cluster" in #59179 broke startup of existing clusters
that used the previously-default cluster name "Test Cluster":
ERROR 23:00:47 Fatal exception during initialization
org.apache.cassandra.exceptions.ConfigurationException: Saved cluster name Test Cluster != configured name NixOS Test Cluster
Fixes#63388.
This will keep configuration configuring the size of the /boot partition
still build, while showing the deprecation warning.
In 99.9% of cases I assume ignoring the configuration is better, as the
sd-image builder already is pretty opinionated in that matter.
The slack, seemingly, accounted for more than the minimum required for
slack plus the two partitions.
This change makes the gap a somewhat abstracted amount, but is not
configurable within the derivation.
The current FAT32 partition is kept as it is required for the Raspberry
Pi family of hardware. It is where the firmware is kept.
The partition is kept bootable, and the boot files kept in there until
the following commits, to keep all commits of this series individually
bootable.
Up until now, the output has been the same for swap devices and swap
files:
{ device = "/var/swapfile"; }
Whereas for swap *files* it's easier to manage them declaratively in
configuration.nix:
{ device = "/var/swapfile"; size = 8192; }
(NixOS will create the swapfile, and later resize it, if the size
attribute is changed.)
With the assumption that swap files are specified in configuration.nix,
it's silly to output them to hardware-configuration.nix.
This will reduce the confusion at boot, where the only thing visible is
the last message from u-boot; where it looks like the board is
hung, while in reality it's likely resizing partitions.

Fixes the broken metrics evaluation which was caused by a `trace`
warning in stdout which confused `jq` in `pkgs/top-level/metrics.nix`.
Also made the `bind-device` feature optional as suggested after the
merge.
Manual build broken by 79f7f89442, which
is part of pull request #59179 (Fix Cassandra, improve config and
tests).
The issue was just a small error because of an unbalanced <literal/>
tag, so only a "/" was missing :-)

The the extraConfig variable is added below the domain variable in the
ddclient config file. The domain variable should always be last.

If the `seedAddresses` is not set, don't force `SimpleSeedProvider` to
be in `seed_provider`. This could cause problems in a multi-datacenter
deployment when a different seed provider is preferred.
Below that it works but only when supplying a custom password file with
restricted permissions (i.e. outside the nix-store). We can't do that
using an absolute path in the tests.
If you're on a multi user system you don't want to have the password in
the nix-store. With the new jmxRolesFile option you can specify your own
protected file instead.
Seems like you can't have a node as its own seed when it's listening on
an interface instead of an IP. At least the way it was done in the
test doesn't work and I can't figure out any other way than to just
listen on the IP address instead.
Add "bcache" to boot.initrd.availableKernelModules if a bcache device is
detected.
This fixes a problem I've had one too many times: I install NixOS and
forget to add "bcache", resulting in an unbootable machine (until fixed
with Live CD). Now NixOS will do it for me.
It is referenced in various places, but does not work out of the box:
$ nixos-help
/run/current-system/sw/bin/nixos-help: unable to start a web browser; please set $BROWSER
In the user-hidden fallbacks to xdg-open(1) and w3m(1), `nixos-help`
expects tools to be deliberately installed by users.
For default installations and new users in general, this is unlikely to
be the case. Conversely, chances to use `nixos-help` are even higher
in such cases.
Use w3m-nographics by default to ensure documentation is always
available. The documentation browser on ttyS8 already does so, but is
not accessible in every installation, e.g. VMs with only ttyS0 and SSH
available.
This obsoletes including it in the base profile's systemPackages,
so remove the @TODO as done.
Previously each oneshot peer service only ran once and was not
restarted together with the interface unit. Because of this,
defined peers were missing after restarting their corresponding
interface unit.
