The cliproxyapi-backup service was failing because backup-and-recover.sh references backup-auth.sh and recover-auth.sh, but only the main script was being copied to the Nix store. This commit creates a backupScripts derivation that bundles all three scripts together, ensuring they're all available in the same directory when the service runs. Fixes exit code 127 (command not found) errors.

Code Review
This pull request correctly identifies and fixes the issue of the cliproxyapi-backup.service failing due to missing script dependencies. Bundling the scripts into a single Nix derivation is a good solution. The changes for the systemd service look solid, including the addition of the PATH environment variable. I've left one comment regarding a potential issue on macOS where the launchd service is missing a similar PATH configuration, which could lead to failures.

While this correctly points the launchd service to the bundled script, it's missing the necessary PATH environment variable for the commands within the scripts to be found on macOS. The backup scripts use commands like aws, ls, and date, which are provided by pkgs.awscli2 and pkgs.coreutils. Without setting the PATH, this service is likely to fail on macOS, similar to the original problem on Linux.
To fix this, you should add an Environment attribute to the config block for this launchd agent, similar to how you've done for the systemd service. It should set a PATH that includes the binaries from awscli2 and coreutils.

The backup service now overrides PATH to only awscli2/coreutils, but backup-and-recover.sh executes backup-auth.sh and recover-auth.sh directly, which rely on their #!/usr/bin/env bash shebangs to find bash. On NixOS (or any system without /usr/bin/bash), env won’t locate bash in this restricted PATH, so the backup cycle fails with env: bash: No such file or directory. Consider adding pkgs.bash to the PATH or invoking the helper scripts via an explicit ${pkgs.bash}/bin/bash.

71-83: Darwin backup service missing PATH environment variable.The Linux systemd backup service (lines 106-111) correctly adds a PATH environment variable including awscli2 and coreutils. However, the Darwin launchd backup service lacks this environment configuration. If the backup scripts require aws CLI commands or coreutils utilities (which is likely given the PR context), this service may fail on macOS.
Consider adding an Environment attribute similar to the main cliproxyapi Darwin service (lines 29-38):
🔎 Proposed fix
launchd.agents.cliproxyapi-backup = lib.mkIf pkgs.stdenv.isDarwin { enable = true; config = { ProgramArguments = [ "${pkgs.bash}/bin/bash" "${backupScripts}/backup-and-recover.sh" ]; + Environment = { + PATH = "${ + lib.makeBinPath [ + pkgs.awscli2 + pkgs.coreutils + ] + }:/opt/homebrew/bin:/usr/local/bin:/usr/bin"; + }; StartInterval = 300; # Run every 5 minutes RunAtLoad = true; StandardOutPath = "/tmp/cliproxyapi-backup.log"; StandardErrorPath = "/tmp/cliproxyapi-backup.error.log"; }; };

11-18: Consider adding more detailed documentation.The backupScripts derivation correctly bundles the three scripts to fix the missing dependency issue. However, per the coding guidelines on documenting complex configurations and major changes, consider expanding the comment to explain why this bundling is needed (e.g., "backup-and-recover.sh sources backup-auth.sh and recover-auth.sh from the same directory, so they must be bundled together in the Nix store").
Based on coding guidelines and learnings about documenting major changes in Nix configurations.

105-111: LGTM! Properly fixes the service failure.The changes correctly address the issue described in the PR objectives:
- Line 105 uses the bundled scripts path, ensuring all dependent scripts are available in the same directory
- Lines 106-111 add the PATH environment variable with awscli2 and coreutils, which the scripts need to execute aws commands and use standard utilities
This should resolve the code 127 (command not found) error.

Pull request overview
This PR fixes a failing cliproxyapi-backup.service on Linux by bundling the main backup script with its dependencies (backup-auth.sh and recover-auth.sh) into a single Nix store directory. Previously, only the main script was copied, causing the service to fail with exit code 127 when trying to execute the dependent scripts.
Key Changes:
- Created a
backupScriptsderivation that bundles all three backup scripts together - Updated both macOS and Linux backup services to reference the bundled scripts
- Added PATH environment variable to the Linux systemd service to include awscli2 and coreutils

- The macOS launchd backup service is missing the Environment configuration with PATH that includes awscli2 and coreutils. The backup scripts (backup-auth.sh and recover-auth.sh) depend on the 'aws' command being available. Without a PATH environment variable, the service may fail on macOS when trying to execute these commands. Consider adding an Environment section similar to the main cliproxyapi service (lines 29-38) that includes awscli2 and coreutils in the PATH.

✅ Addressed in 6c1708a
The service needs bash in PATH to execute the backup scripts that call other scripts using SCRIPT_DIR.
Summary
cliproxyapi-backup.servicewhich was degrading the systemd sessionRoot Cause
The

✅ Service is now running successfully on the fix branch
✅ Systemd session is no longer degraded (0 failed units)
✅ Backup and recovery cycle completes without errors
