* nixos/k3s: simplify config expression
* nixos/k3s: add config assertions and trim unneeded bits
* nixos/k3s: add a test that k3s works; minor module improvements
This is a single-node test. Eventually we should also have a multi-node
test to verify the agent bit works, but that one's more involved.
* nixos/k3s: add option description
* nixos/k3s: add defaults for token/serveraddr
Now that the assertion enforces their presence, we dont' need to use the typesystem for it.
* nixos/k3s: remove unneeded sudo in test
* nixos/k3s: add to test list
This reverts commit 5532065d06.
As far as I can tell setting RemainAfterExit=true here completely breaks
certificate renewal, which is really bad!
the sytemd timer will activate the service unit every OnCalendar=,
however with RemainAfterExit=true the service is already active! So the
timer doesn't rerun the service!
The commit also broke the actual tests, (As it broke activation too)
but this was fixed later in https://github.com/NixOS/nixpkgs/pull/76052
I wrongly assumed that PR fixed renewal too, which it didn't!
testing renewals is hard, as we need to sleep in tests.
For reasons yet unknown, the vxlan backend doesn't work (at least inside
the qemu networking), so this is moved to the udp backend.
Note changing the backend apparently also changes the interface name,
it's now `flannel0`, not `flannel.1`

This was whitespace-sensitive, kept fighting with my editor and broke
the tests easily. To fix this, let python convert the output to
individual lines, and strip whitespace from them before comparing.
When trying to build a VM using `nixos-build-vms` with a configuration
that doesn't evaluate, an error "at `<unknown-file>`" is usually shown.
This happens since the `build-vms.nix` creates a VM-network of
NixOS-configurations that are attr-sets or functions and don't contain
any file information. This patch manually adds the `_file`-attribute to
tell the module-system which file contained broken configuration:
```
$ cat vm.nix
{ vm.invalid-option = 1; }
$ nixos-build-vms vm.nix
error: The option `invalid-option' defined in `/home/ma27/Projects/nixpkgs/vm.nix@node-vm' does not exist.
(use '--show-trace' to show detailed location information)
```
This commit:
1. Updates the path of the traefik package, so that the out output is
used.
2. Adapts the configuration settings and options to Traefik v2.
3. Formats the NixOS traefik service using nixfmt.
According to my analysis the last critical fix went into v5.4.23, I have
confirmed this by running WebGL over night and haven't seen a single
i915 GPU hang. Lets remove the notes from the release notes.
