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.

Environment file as defined in {manpage}`systemd.exec(5)`.
|
|
|
|
Secrets may be passed to the service without adding them to the
|
|
world-readable Nix store, by specifying placeholder variables as
|
|
the option value in Nix and setting these variables accordingly in the
|
|
environment file.
|
|
|
|
By default, Litestream will perform environment variable expansion
|
|
within the config file before reading it. Any references to ''$VAR or
|
|
''${VAR} formatted variables will be replaced with their environment
|
|
variable values. If no value is set then it will be replaced with an
|
|
empty string.
|
|
|
|
```
|
|
# Content of the environment file
|
|
LITESTREAM_ACCESS_KEY_ID=AKIAxxxxxxxxxxxxxxxx
|
|
LITESTREAM_SECRET_ACCESS_KEY=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/xxxxxxxxx
|
|
```
