...but still allow for setting `dataDir` to a custom path. This gets
rid of the use of the deprecated option PermissionsStartOnly. Also, add
the ability to customize user and group, since that could be useful
with a custom `dataDir`.
By default, pgadmin4 uses SERVER_MODE = True. This requires
access to system directories (e.g. /var/lib/pgadmin). There is
no easy way to change this mode during runtime. One has to change
or add config files withing pgadmin's directory structure to change it
or add a system-wide config file under `/etc/pgadmin`[1].
This isn't always easy to achive or may not be possible at all. For
those usecases this implements a switch in the pgadmin4 derivation and
adds a new top-level package `pgadmin4-desktopmode`. This builds in
DESKTOP MODE and allows the usage of pgadmin4 without the nixOS module
and without access to system-wide directories.
pgadmin4 module saves the configuration to /etc/pgadmin/config_system.py
pgadmin4-desktopmode tries to read that as well. This normally fails with
a PermissionError, as the config file is owned by the user of the pgadmin module.
With the check-system-config-dir.patch this will just throw a warning
but will continue and not read the file.
If we run pgadmin4-desktopmode as root
(something one really shouldn't do), it can read the config file and fail,
because of the wrong config for desktopmode.

We test pgadmin in nixosTests, because it needs a running postgresql instance.
This is now unnecessary since we can do so in the package itself.
This reduces the complexity of pgadmin and removes the need for the extra
nixosTests.
Also setting SERVER_MODE in `pkg/pip/setup_pip.py` does not have any effect
on the final package, so we remove it.
In NixOS, we use the module, which expects SERVER_MODE to be true (which it defaults to).
In non-NixOS installations, we will need the directory /var/lib/pgadmin and /var/log/pgadmin

Previously, secrets were named according to the initrd they were
associated with. This created a problem: If secrets were changed whilst
the initrd remained the same, there were two versions of the secrets
with one initrd. The result was that only one version of the secrets would
by recorded into the /boot partition and get used. AFAICT this would
only be the oldest version of the secrets for the given initrd version.
This manifests as #114594, which I found frustrating while trying to use
initrd secrets for the first time. While developing the secrets I found
I could not get new versions of the secrets to take effect.
Additionally, it's a nasty issue to run into if you had cause to change
the initrd secrets for credential rotation, etc, if you change them and
discover you cannot, or alternatively that you can't roll back as you
would expect.
Additional changes in this patch.
* Add a regression test that switching to another grub configuration
with the alternate secrets works. This test relies on the fact that it
is not changing the initrd. I have checked that the test fails if I
undo my change.
* Persist the useBootLoader disk state, similarly to other boot state.
* I had to do this, otherwise I could not find a route to testing the
alternate boot configuration. I did attempt a few different ways of
testing this, including directly running install-grub.pl, but what
I've settled on is most like what a user would do and avoids
depending on lots of internal details.
* Making tests that test the boot are a bit tricky (see hibernate.nix
and installer.nix for inspiration), I found that in addition to
having to copy quite a bit of code I still couldn't get things to
work as desired since the bootloader state was being clobbered.
My change to persist the useBootLoader state could break things,
conceptually. I need some help here discovering if that is the case,
possibly by letting this run through a staging CI if there is one.
Fix#114594.

This commit fixes a papercut in nixos-rebuild where people wanting to
switch to a specialisation (or test one) were forced to manually figure
out the specialisation's path and run its activation script - since now,
there's a dedicated option to do just that.
This is a backwards-compatible change which doesn't affect the existing
behavior, which - to be fair - might still be considered sus by some
people, the painful scenario here being:
- you boot into specialisation `foo`,
- you run `nixos-rebuild switch`,
- whoops, you're no longer at specialisation `foo`, but you're rather
brought back to the base system.
(it's especially painful for cases where specialisation is used to load
extra drivers, e.g. Nvidia, since then launching `nixos-rebuild switch`,
while forgetting that you're inside a specialisation, can cause some
parts of your system to get accidentally unloaded.)
I've tried to mitigate that by improving specialisations so that they
create a dedicated file somewhere in `/run/current-system` containing
the specialisation's name (which `nixos-rebuild` could then use as the
default value for `--specialisation`), but I haven't been able to come
up with anything working (plus it would be a breaking change then).
