Current journal output from services started by `script` rather than
`ExexStart` is unreadable because the name of the file (which journalctl
records and outputs) quite literally takes 1/3 of the screen (on smaller
screens).
Make it shorter. In particular:
* Drop the `unit-script` prefix as it is not very useful.
* Use `writeShellScriptBin` to write them because:
* It has a `checkPhase` which is better than no checkPhase.
* The script itself ends up having a short name.
systemd-tmpfiles will load all files in lexicographic order and ignores rules
for the same path in later files with a warning Since we apply the default rules
provided by systemd, we should load user-defines rules first so users have a
chance to override defaults.
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.
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.
We already set the relevant env vars in the systemd services. That does
not help one when executing any of the executables outside a service,
e.g. when creating a new user.
we use stdenv.hostPlatform.uname.processor, which I believe is just like
`uname -p`.
Example values:
```
(import <nixpkgs> { system = "x86_64-linux"; }).stdenv.hostPlatform.uname.processor
"x86_64"
(import <nixpkgs> { system = "aarch64-linux"; }).stdenv.hostPlatform.uname.processor
aarch64
(import <nixpkgs> { system = "armv7l-linux"; }).stdenv.hostPlatform.uname.processor
"armv7l"
```
