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.

NixOS version name to be used in the names of generated
|
|
outputs and boot labels.
|
|
|
|
If you ever wanted to influence the labels in your GRUB menu,
|
|
this is the option for you.
|
|
|
|
It can only contain letters, numbers and the following symbols:
|
|
`:`, `_`, `.` and `-`.
|
|
|
|
The default is {option}`system.nixos.tags` separated by
|
|
"-" + "-" + {env}`NIXOS_LABEL_VERSION` environment
|
|
variable (defaults to the value of
|
|
{option}`system.nixos.version`).
|
|
|
|
Can be overridden by setting {env}`NIXOS_LABEL`.
|
|
|
|
Useful for not loosing track of configurations built from different
|
|
nixos branches/revisions, e.g.:
|
|
|
|
```
|
|
#!/bin/sh
|
|
today=`date +%Y%m%d`
|
|
branch=`(cd nixpkgs ; git branch 2>/dev/null | sed -n '/^\* / { s|^\* ||; p; }')`

revision=`(cd nixpkgs ; git rev-parse HEAD)`
