DANE provides user friction…but as OP mentioned TLS doesn’t work

Maybe not apt…but sudo dnf install nix nix-daemon

Not too difficult to fix this in post.

1. Turn off, boot from a USB
2. Copy all home to drive
3. Delete home from old drive
4. Add fstab entry
5. ???
6. Lose all data (but usually profit)
