Introduce a new .plasma5.phononBackend option. Default value
"gstreamer" installs the same packages as before. "vlc" installs
only the vlc phonon backend.
Left to do: re-enable as needed in the usual situations.
This added ~286MiB to the base system closure, which is enough to bring
the sd images over the limit allowed on Hydra.
In commit d43dc68db3, @Mic92 split the
rootpw option to allow specifying it in a file kept outside the Nix
store, as an alternative to specifying the password directly in the
config.
Prior to that, rootpw's type was `str`, but in order to allow both
alternatives, it had to become `nullOr str` with a default of `null`. So
I can see why this assertion, that either rootpw or rootpwFile are
specified, makes sense to add here.
However, these options aren't used if the configDir option is set, so as
written this assertion breaks valid configurations, including the
configuration used by nixos/tests/ldap.nix.
So this patch fixes the assertion so that it doesn't fire if configDir
is set.
The old open-source driver for AMD/ATI GPUs is commonly known as "radeon"
despite the historical package name xf86-video-ati. For example it presents
itself as RADEON in the Xorg log. So adding "radeon" to videoDrivers should
work.
Also changed the docs for the videoDrivers option to use "radeon" in the
default value instead of "ati".
Fixes #37917
This is a refactor of how resolvconf is managed on NixOS. We split it
into a separate service which is enabled internally depending on whether
we want /etc/resolv.conf to be managed by it. Various services now take
advantage of those configuration options.
We also now use systemd instead of activation scripts to update
resolv.conf.
NetworkManager now uses the right option for rc-manager DNS
automatically, so the configuration option shouldn't be exposed.
The new option services.postfix.localRecipients allows
configuring the postfix option 'local_recipient_maps'. When
set to a list of user names (or patterns), that map
effectively replaces the lookup in the system's user
database that's used by default to determine which local
users are valid.
This option is useful to explicitly set local users that are
allowed to receive e-mail from the outside world. For local
injection i.e. via the 'sendmail' command this option has no
effect.
This commit brings a module that installs the
IBM Spectrum Protect (Tivoli Storage Manager)
command-line client together with its
system-wide client system-options file `dsm.sys`.
We were already creating a group for the user under which to run syncthing but
we were defaulting to running as `nogroup`.
Additionally, use `install` instead of multiple calls to mkdir/cp/chown.
NixOS usually needs nscd just to have a single place where
LD_LIBRARY_PATH can be set to include all NSS modules, but nscd is also
useful if some of the NSS modules need to read files which are only
accessible by root.
For example, nixos/modules/config/ldap.nix needs this when
users.ldap.enable = true;
users.ldap.daemon.enable = false;
and users.ldap.bind.passwordFile exists. In that case, the module
creates an /etc/ldap.conf which is only readable by root, but which the
NSS module needs to read in order to find out what LDAP server to
connect to and with what credentials.
If nscd is started as root and configured with the server-user option in
nscd.conf, then it gives each NSS module the opportunity to initialize
itself before dropping privileges. The initialization happens in the
glibc-internal __nss_disable_nscd function, which pre-loads all the
configured NSS modules for passwd, group, hosts, and services (but not
netgroup for some reason?) and, for each loaded module, calls an init
function if one is defined. After that finishes, nscd's main() calls
nscd_init() which ends by calling finish_drop_privileges().
There are provisions in systemd for using DynamicUser with a service
which needs to drop privileges itself, so this patch does that.
Until now the startup failed with an error like this:
```
com.github.joschi.jadconfig.ValidationException: Parent path /var/lib/graylog/server for Node ID file at /var/lib/graylog/server/node-id is not a directory
```
This happens since `graylog.service` ensures that `/var/lib/graylog`
exists, however it doesn't take care of the directory for
`cfg.nodeIdFile`.
Thanks to @arianvp for pointing out that when DynamicUser is true,
systemd defaults the value of User to be the name of the unit, which in
this case is already "nscd".
This is more robust than setting via environment variable, though it does come
later in the load sequence. An added benefit is affecting the current
session.
These options were being set to the same value as the defaults that are
hardcoded in nscd. Delete them so it's clear which settings are actually
important for NixOS.
One exception is `threads 1`, which is different from the built-in
default of 4. However, both values are equivalent because nscd forces
the number of threads to be at least as many as the number of kinds of
databases it supports, which is 5.
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.
