Problem: Restarting (stopping) system.slice would not only stop X11 but
also most system units/services. We obviously don't want this happening
to users when they switch from 18.03 to 18.09 or nixos-unstable.
Reason: The following change in systemd:
d8e5a93382
The commit adds system.slice to the perpetual units, which means
removing the unit file and adding it to the source code. This is done so
that system.slice can't be stopped anymore but in our case it ironically
would cause this script to stop system.slice because the unit file was
removed (and an older systemd version is still running).

Rather than special-casing the dns options in networkmanager.nix, use
the module system to let unbound and systemd-resolved contribute to
the newtorkmanager config.
find-libs is currently choking when it finds the dynamic linker
as a DT_NEEDED dependency (from glibc) and bails out like this
(as glibc doesn't have a RPATH):
Couldn't satisfy dependency ld-linux-x86-64.so.2
Actually the caller of find-libs ignores the exit status, so the issue
almost always goes unnoticed and happens to work by chance. But
additionally what happens is that indirect .so dependencies are
left out from the dependency closure calculation, which breaks
latest cryptsetup as libssl.so isn't found anymore.

The correct way to override a single value would be to use something
like this:
systemd.services.nagios.serviceConfig.Restart = lib.mkForce "no";
However, this doesn't work because the check is applied for the attrsOf
type and thus the attribute values might still contain the attribute set
created by mkOverride.
The unitOption type however did already account for this, but at this
stage it's already too late.
So now the actual value is unpacked while checking the values of the
attribute set, which should allow us to override values in
serviceConfig.

When a package contains a directory in one of the systemd directories
(like flatpak does), it is symlinked into the *-units derivation.
Then later, the derivation will try to create the directory, which
will fail:
mkdir: cannot create directory '/nix/store/…-user-units/dbus.service.d': File exists
builder for '/nix/store/…-user-units.drv' failed with exit code 1
Closes: #33233
GRUB 2.0 supports png, jpeg and tga. This will use the image's suffix to
load the right module.
As jpeg module is named jpeg, jpg is renamed jpeg.
If the user uses wrong image suffix for an image, it wouldn't work anyway.
This will leave up to two additional left-over files in /boot/ if user switches
through all the supported file formats. The module already left the png
image if the user disabled the splash image.
This is apparent from the service file directory in plymouth:
├── multi-user.target.wants
│ ├── plymouth-quit.service -> ../plymouth-quit.service
│ └── plymouth-quit-wait.service -> ../plymouth-quit-wait.service
Leaving it unspecified caused gdm-wayland to crash on boot, see #39615.
The change made other display managers not quit plymouth properly however. By
removing "multi-user.target" from `plymouth-quit.after` this is resolved.
