The original idea for this test was, on top of providing a networkd
test, to provide newcomers with a sample configuration they could use
to get started with networkd.
That's precisely why we were doing this systemd tmpfile dance in the
first place. It was a convenient way to create a runtime file with a
specific mode and owner.
Sadly, this tmpfile rule made the test flaky. There's a race condition
between the wireguard interface configured by systemd-networkd and
systemd-tmpfiles-setup.
Sometimes, networkd is going to try loading the wireguard private key
file *before* the said file gets created by systemd-tmpfiles.
A perfect solution here would be to create a "After" dependency
between wg0.netdev and systemd-tmpfiles-setup.service. Sadly, it is
currently impossible to create such a dependency between a
networkd-specific unit and a service.
We're removing this tmp file in favor of pointing networkd directly to
the Nix store. This is clearly something that shouldn't be done in the
real world for a private file: the store is world-readable. However,
this is the only way I found to fix this test flakiness for now.
In `systemd-243` the option `FwMark` in the `[WireGuard]` section of
a `.netdev`-unit has been renamed to `FirewallMark`[1]. Due to the
removal of deprecated options in our `networkd` module[2] the evaluation
of this test doesn't work.
Renaming the option to its new name fixes the issue.

... and remove some weirdnesses.
- Port to Python
- Drop the extra pkgs, config, system args
- Drop all `with`
- Don't override the standard PostgreSQL directory
- Use pkgs and lib from the test runner
Tested with:
- postgresql_12
- postgresql_11
- postgresql_10
- postgresql_9_6
- postgresql_9_5

According to RFC4291[1], 2001:db8:: is the anycast address for the
prefix and will be answered by all routers responsible for this prefix.
This means that before the iputils bump, the ping from client to isp was
answered by the router and not by the ISP machine. Switching away from
the anycast address fixes this issue.

This test wants to download things from the internet while building the
system. It can probably be fixed by ensuring these paths are present in
the initial nix-store.
This appears to avoid requiring KVM when it’s not available. This is
what I originally though -cpu host did. Unfortunately not much
documentation available from the QEMU side on this, but this appears
to square with help:
$ qemu-system-x86 -cpu help
...
x86 host KVM processor with all supported host features
x86 max Enables all features supported by the accelerator in the current host
...
Whether we actually want to support this not clear, since this only
happens when your CPU doesn’t have full KVM support. Some Nix builders
are lying about kvm support though. Things aren’t too slow without it
though.

Looks like `nix ping-store` does not output anything anymore but still
fails when the connection does not work.
Since systemd 243, docs were already steering users towards using
`journal`:

systemd 246 will go one step further, it shows warnings for these units
during bootup, and will [automatically convert these occurences to
`journal`](f3dc6af20f):
> [ 6.955976] systemd[1]: /nix/store/hwyfgbwg804vmr92fxc1vkmqfq2k9s17-unit-display-manager.service/display-manager.service:27: Standard output type syslog is obsolete, automatically updating to journal. Please update│······················
your unit file, and consider removing the setting altogether.
So there's no point of keeping `syslog` here, and it's probably a better
idea to just not set it, due to:
> This setting defaults to the value set with DefaultStandardOutput= in
> systemd-system.conf(5), which defaults to journal.
This creates and opens a luks volume, puts its passphrase into a keyfile
and writes a /etc/crypttab. It then reboots the machine, and verifies
systemd parsed /etc/crypttab properly, and was able to unlock the volume
with the keyfile provided (as we try to mount it).
The memorySize of the VM had to be bumped, as luksFormat would otherwise
run out of memory.
Cookie jar can be used to accurately test if the login was successful.
Simply searching for the user name is not sufficient, since it is always
part of the returned page after login. The page should display a phrase
containing the username after login.
