This minimal SnapRAID script is based on https://github.com/auanasgheps/snapraid-aio-script
I tried other SnapRAID scripts written for Ubuntu/Debian they didn't play well with Void/Slackware.
This script and the snapraid-aio-script appears to work correctly.
mklog
pip install mklog
snapraid
xbps-install snapraid
