Has anyone tried using SELinux on OMV?
Considering the use case for OMV is often internet-facing (eg. Nextcloud), and/or contains important files/backups, and/or involves containers which vary widely in quality, SELinux would be perfect for those who are more security-conscious and don't mind tinkering to get things working right.
