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

Definitely not available. I believe this is a raspbian-only thing?

Thanks for your input
