I am pretty sure the kernel is up to date, but I am not 100% sure since I haven’t checked that the process didn’t fail at some point. This is a tertiary backup system, super low priority, hosting movies, music, and VeraCrypt drives internally behind multiple layers of network security and isolated in the DMZ where I keep stuff I want isolated from my network, like SmartTVs, IOT crap, and gaming consoles. But since I am working on it now, I will double check.
EDIT: 6.9.3, which is a little behind, but I’m ok with that.
