lib + bespoke: ...
- Implement Lua package set override functionality
- Add some Lua packages: moonscript, moonpick, and argparse (a
dependency of moonscript)
buildPythonOverrides: move to lib namespace
Add lib directory for re-usable function library
backups: improve set_backup_acls behaviour
- Change it to runing on a 1-hour timer, as well as shortly after boot.
This way we catch any new files/folders created with bad permissions.
