This adds an `extraConfig` option to timesyncd for setting additional
options in `/etc/systemd/timesyncd.conf`.
This is similar to things like `services.journald.extraConfig` and
`services.logind.extraConfig`.
The new description should give more clear understanding of when to
edit the option.
I used NixOS to set up a DNS server that is authoritative for certain
zones. The description of the `cacheNetworks` option made me think I
needed to set it to `"any"` to allow people to query the zone I set
up. Reading the source of the module would have clarified my
understanding, but at the time I just read the description and thought
little of it. Later I discovered I was getting tons of DNS requests
and presumably being used for a DNS amplification attack or similar.
I have fixed the problem now, but I would like the option to have a
clearer description so others don't make the same mistake I did.
This has been there since v209 [1]
```
The interface name to use. This option has lower precedence than NamePolicy=, so for this setting to take effect, NamePolicy= must either be unset, empty, disabled, or all policies configured there must fail. Also see the example below with "Name=dmz0".
Note that specifying a name that the kernel might use for another interface (for example "eth0") is dangerous because the name assignment done by udev will race with the assignment done by the kernel, and only one interface may use the name. Depending on the order of operations, either udev or the kernel will win, making the naming unpredictable. It is best to use some different prefix, for example "internal0"/"external0" or "lan0"/"lan1"/"lan3".

most likely, people enabling the lorri module also want to use it,
without explicitly having to add it to users.users.<username>.packages.

Add a virtual user system based around pam and a Berkeley
user database.
Adding the:
- localRoot
- userDbPath
- allowWriteableChroot
- virtualUseLocalPrivs
Vsftpd options.
Ever since setting up bonding the `wpa_supplicant-unit-start` script has
been failing. This is because the file `bonding_masters` in
`/sys/class/net/` is *not* a directory containing `uevent`.
Adding a test to verify the `uevent` path to be sourced exists resolves
the problem.
The SLIM project is abandoned and their last release was in 2013.
Because of this it poses a security risk to systems, no one is working
on it or picked up maintenance. It also lacks compatibility with systemd
and logind sessions. For users, there liikely isn't anything like slim
that's as lightweight in terms of dependencies.
Slurmdbd requires a password database which is stored in slurmdbd.conf.
A seperate config file avoids that the password ends up in the nix store.
Slurmdbd does 19.5 does not support MySQL socket conections.
Adapated the slurm test to provide username and password.
* Fix path in module for slurm to find plugstack.conf
* Fix configure flags so that slurm can be compiled
without internal X11 support (required for spank-x11).
This prevents services to be started before they're initialized, and
renders the `systemd.targets.ceph.wantedBy = lib.mkForce [];` hack in
the vm tests obsolete - The config now starts up ceph after a reboot,
too.
Let's take advantage of that, crash all VMs, and boot them up again.
Don't pass user and group to ceph, and rely on it to drop ceps, but let
systemd handle running it as the appropriate user.
This also inlines the extraServiceConfig into the makeService function,
as we have conditionals depending on daemonType there anyways.
Use StateDirectory to create directories in
/var/lib/ceph/${daemonType}/${clusterName}-${daemonId}.
There previously was a condition on daemonType being one of mds,mon,rgw
or mgr. We only instantiate makeServices with these types, and "osd" was
special.
In the osd case, test examples suggest it'd be in something like
/var/lib/ceph/osd/ceph-${cfg.osd0.name} - so it's not special at all,
but exactly like the pattern for the others.
During initialization, we also need these folders, before the unit is
started up. Move the mkdir -p commands in the vm tests to the line
immediately before they're required.
The two new options make it possible to create the interface in one namespace
and move it to a different one, as explained at https://www.wireguard.com/netns/.
In cases where you boot up really quickly (like in the VM test on a
non-busy host), tinydns might want to bind before the loopback interface
is fully up. Order tinydns after network.target to fix that.
Add --use-remote-sudo option. When set, remote commands will be prefixed
with 'sudo'. This allows using sudo remotely _without_ having to use
sudo locally (when using --build-host/--taget-host).
Incorrect merging of modules resulted in dhcpcd being enabled causing flaky network connection.
https://github.com/NixOS/nixpkgs/pull/64364
Fixing it uncovered an infinite recursion from the same commit, previously masked by the incorrect merge.
We can just drop the `mkDefault` for `networking.wireless.enable` as it is already `false` by default.

When we did the revert of adding gnome-flashback to systemd.packages [0]
I forgot to test with other display managers. If we use GDM with gnome-flashback
it appears it doesn't try to fallback to non-systemd startup and always fails and
starts the regular gnome-session. So adding gnome-flashback to systemd.packages
was perfectly fine, but we did forgot one detail. We need systemd targets for the
customSessions which is added using mkSystemdTargetForWm in the gnome-
flashback package.

When the option services.vault.storageBackend is set to "file", a
systemd.tmpfiles.rules was added, with extraneous []. These are not
needed and have been removed.
This is a good example of a package/module that should be distributed
externally (e.g. as a flake [1]): it's not stable yet so anybody who
seriously wants to use it will want to use the upstream repo. Also,
it's highly specialized so NixOS is not really the right place at the
moment (every NixOS module slows down NixOS evaluation for everybody).

Automated consumers can use 'sed 1d' or similar to remove this header.
This probably makes this output *easier* to consume correctly. Having
this header show up in consumers' terminal or log output is probably not
useful, but hiding it without hiding all error messages would have been
more troublesome that just stripping it from stdout.
I.e., previously, unsophisticated use would show undesired output:
$ some-other-tool
This attribute set contains:
This attribute set contains:
This attribute set contains:
This attribute set contains:
<Actual some-other-tool output>
The simplest way to hide this undesired output would have been
nixos-option ... 2>/dev/null, which would hide all error messages.
We do not wish to encourage that.
Correct use would have been something like:
nixos-option ... 2> >( grep --line-buffered -v 'This attribute set contains:')
After this change, correct use is simpler:
nixos-option ... | sed 1d
or
nixos-option ... | sed '1/This attribute set contains:/d'
if the caller don't know if this invocation of nixos-option will yield
an attribute listing or an option description.

I don't think this matters. As long as one or the other of these is
a std::string, I get an operator== that looks at content rather than
pointer equality. I picked casting the constant over casting the dynamic
thing in hopes that the compiler would have a better chance at optimizing
away any runtime cost.
Deferring to reviewer.
