I consider myself a Debian root. I maintain DNS instances, install YunoHost and a number of userland stuff. I do this for years, maybe even for a decade. I know how to install, backup, restore, upgrade and migrate my namespace and all other services including LDAP, email, etc.
I wish everyone knew this much, I can train anyone to learn this much.
UNIX roots who know everything might look down on me, but even they cannot deny the internet would be in a far better shape if the LUGs managed to hang around longer - or we could bring them back and re-purpose them for portals, fediverse, IPFS, blockchain.
