After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.
Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.
A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.

Alloy configuration file/directory path.
|
|
|
|
We default to `/etc/alloy` here, and expect the user to configure a
|
|
configuration file via `environment.etc."alloy/config.alloy"`.
|
|
|
|
This allows config reload, contrary to specifying a store path.
|
|
A `reloadTrigger` for `config.alloy` is configured.
|
|
|
|
Other `*.alloy` files in the same directory (ignoring subdirs) are also
|
|
honored, but it's necessary to manually extend
|
|
`systemd.services.alloy.reloadTriggers` to enable config reload
|
|
during nixos-rebuild switch.
|
|
|
|
This can also point to another directory containing `*.alloy` files, or
|
|
a single Alloy file in the Nix store (at the cost of reload).
|
|
|
|
Component names must be unique across all Alloy configuration files, and
|
|
configuration blocks must not be repeated.
|
|
|
|
Alloy will continue to run if subsequent reloads of the configuration
|
|
file fail, potentially marking components as unhealthy depending on
|
|
the nature of the failure. When this happens, Alloy will continue
|
|
functioning in the last valid state.
