That's correct, it's Devuan (a debian non-systemd derivative). I've never used raspbian (I don't like systemd). Devuan (from Ascii to Beowulf - they're the versions) has been what it's running the last 4 years. I decided to attempt a migration to FreeBSD but given the awful network speeds, that's probably not feasible. That's why I am here :0( > # vcgencmd otp_dump | grep 30: > > should work to find the revision code. But > it failed to initialize on Fedora 34. Definitely not available. I believe this is a raspbian-only thing? Thanks for your input Matt.
