The Opensnitch version offered by the Garuda assistant doesn't seem to install correctly.
The Opensnitch daemon doesn't start when the main GUI is launched, I have to enter commands found here to start the daemon and the opensnitch service. After these are entered blocking resumes as normal. Nothing I tried in the GUI would start outbound connection monitoring.
Outbound connection prompting doesn't survive a reboot. (I gave up troubleshooting here as setting the autostart option in the GUI, didn't function and I figured I would try and get help from more experienced users).
