lib/test.nix relies on `fileset.toSource` which creates a source dir
with the files of interest. `testers.shellcheck` passes all the files in
the source dir to shellcheck. The issue is related to relative path
sourcing, i.e. `source ./lib.sh` where shellcheck cannot make any
assumptions about the working directory.
Options were:
1) Disable this warning with a directive
Prior disabling in the tree:
- pkgs/tools/nix/info/info.sh
- nixos/modules/testing/test-instrumentation.nix
2) Set source-path to SCRIPTDIR with a directive
https://github.com/koalaman/shellcheck/wiki/Directive#source-path
Even though we don't enable external script following for shellcheck
with `-x` flag given every file in the source dir is passed, this
directive seems to capture the intent to help shellcheck a bit
better.
Went with option 2.
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.
