The redis module currently fails to start up, most likely due to running
a chown as non-root in preStart.
While at it, I hardcoded it to use systemd's StateDirectory and
DynamicUser to manage directory permissions, removed the unused
appendOnlyFilename option, and the pidFile option.
We properly tell redis now it's daemonized, and it'll use notify support
to signal readiness.
In fontconfig’s 60-generic.conf, order of preference is estabilished for emoji
font family. Because fontconfig parses the config files in lexicographic order,
appending each <prefer> from <alias> element to the family’s prefer list
(to be prepended before the family) [1], our font family defaults stored
in 52-nixos-default-fonts.conf will take precedence. That is, of course, unless
the default „weak“ binding [2] is used. Emoji family binds strongly [3],
so we need to set binding to “same” for our <alias>es to be considered before
the ones from 60-generic.conf.
By default, we will set the option to all emoji fonts supported by fontconfig,
so that emoji works for user if they have at least one emoji font installed.
If they have multiple emoji fonts installed, we will use the fontconfig’s
order of preference [4].

With local-fs.target part of sysinit.target
(https://github.com/NixOS/nixpkgs/pull/61321), we don't need to add it
explicitly to certain units anymore, and can change dependencies like
they are in other distros (I picked from Google's official CentOS 7
image here).
Like them, use StandardOutput=journal+console to pipe google-*.service
output to the serial console as well.
It turns out that checking for the last mount time of an ext4 file
system isn't a very reliable way to check whether the file system was
properly unmounted.
When creating that test in the first place (88530e02b6),
I was reluctant to inspect the file system when the VM is down and was
searching for a way to check for a clean unmount *after* the file system
was mounted again to make sure we don't need to create a 512 MB raw
image on the host.
Fortunately however, when converting from qcow2, qemu-img actually
writes a sparse file, so for most file systems (that is, file systems
supporting sparse files) this shouldn't waste a lot of disk space.
So when investigating the flakiness, I found that whenever the test is
failing, the unmount of /test-x-initrd-mount was done *before* the final
step during which systemd remounts+unmounts all the remaining file
systems.
I haven't investigated why this is the case, but the test is a
regression test for https://github.com/NixOS/nixpkgs/issues/35268, which
actually didn't unmount the file system *at* *all*, so really all we
need to take care here is whether the unmount has happened and not
*how*.
To make sure that checking the filesystem state is enough for this, I
temporarily replaced the $machine->shutdown call with $machine->crash
and verified that the file system state is "not clean".

Adds:
- gnome-color-manager
- services.avahi
It appears that GeoClue requires its daemon and IIRC has
been default enabled in other distros for a while.
- orca
It's the default screen-reader.
It currently lacks an emoji font-family which means it has to be
disabled for them to function [0]. Additionally it's fallen out of
necessity to ship custom font rendering settings (as far as I'm aware
of).

Any system uid will do, so we let the system allocate
one for us. The 'mailman' group is gone entirely since
we don't need it. Users who wish to run the 'mailman'
administration utility can do so via 'sudo':
$ sudo -u mailman mailman info
Also, simplify the syntax of our user.users entry to
rely on an attribute set rather than a list.
That's one of my itches - when I'm sshing from Emacs' term to a NixOS
machine, it doesn't detect that I'm running emacs and showing a title
escape sequence. This commit fixes it, checking against $TERM to
prevent this from ever bothering anyone again.
* nixos/acme: Fix ordering of cert requests
When subsequent certificates would be added, they would
not wake up nginx correctly due to target units only being triggered
once. We now added more fine-grained systemd dependencies to make sure
nginx always is aware of new certificates and doesn't restart too early
resulting in a crash.
Furthermore, the acme module has been refactored. Mostly to get
rid of the deprecated PermissionStartOnly systemd options which were
deprecated. Below is a summary of changes made.
* Use SERVICE_RESULT to determine status
This was added in systemd v232. we don't have to keep track
of the EXITCODE ourselves anymore.
* Add regression test for requesting mutliple domains
* Deprecate 'directory' option
We now use systemd's StateDirectory option to manage
create and permissions of the acme state directory.
* The webroot is created using a systemd.tmpfiles.rules rule
instead of the preStart script.
* Depend on certs directly
By getting rid of the target units, we make sure ordering
is correct in the case that you add new certs after already
having deployed some.
Reason it broke before: acme-certificates.target would
be in active state, and if you then add a new cert, it
would still be active and hence nginx would restart
without even requesting a new cert. Not good! We
make the dependencies more fine-grained now. this should fix that
* Remove activationDelay option
It complicated the code a lot, and is rather arbitrary. What if
your activation script takes more than activationDelay seconds?
Instead, one should use systemd dependencies to make sure some
action happens before setting the certificate live.
e.g. If you want to wait until your cert is published in DNS DANE /
TLSA, you could create a unit that blocks until it appears in DNS:
```
RequiredBy=acme-${cert}.service
After=acme-${cert}.service
ExecStart=publish-wait-for-dns-script
```
The custom session script is always executed (when it exists). This change
passes the selected session script and select session name to the custom session
script, so that it can defer to the selected session script based on the value
of the selected session name.
The `keys.target` is used to indicate whether all NixOps keys were
successfully uploaded on an unattended reboot. However this can cause
startup issues e.g. with NixOS containers (see #67265) and can block
boots even though this might not be needed (e.g. with a dovecot2
instance running that doesn't need any of the NixOps keys).
As described in the NixOps manual[1], dependencies to keys should be
defined like this now:
``` nix
{
systemd.services.myservice = {
after = [ "secret-key.service" ];
wants = [ "secret-key.service" ];
};
}
```
However I'd leave the issue open until it's discussed whether or not to
keep `keys.target` in `nixpkgs`.

This introduces the following options under the services.gnome3 namespace:
* core-os-services.enable
* core-shell.enable
* core-utilities.enable
* games.enable
The first three are all default enabled by gnome3.enable
and their purpose is to make gnome3 more flexable for users
usecases. In the case of core-utilities and games, it allows
users to easily switch on the default gnome3 applications
and games packages. Previously we had lists in gnome-3/default.nix
but they weren't visible to the user. By having options we have
generated documentation and an interface.
Pretty useful for laptops. I use them with:
```
services.logind.lidSwitch = "suspend-then-hibernate";
environment.etc."systemd/sleep.conf".text = "HibernateDelaySec=8h";
```
We don’t want any trailing whitespace, otherwise we mess up the
formating of the shadow file. Some things like readFile may have the
trailing new line.
Fixes#66745
For some reason nm-applet has to be running for an authentication
dialog to be spawned by wingpanel-indicator-network.
This also fixes storing NetworkManager secrets in the keyring, but this
is still broken because we lack the proper PAM configuration.
