I wanted time machine support over samba so I installed samba version 4.8.5 from Debian testing and I think I have a problem with my config.
First, the server shows up twice in finder, first as "ROCK64" and then as "rock64 - SMB/CIFS". Why is it showing up twice?
Second, when I try to use time machine, I get an error from MacOS Mojave saying the disk has changed and it rewrites the entire backup.
Everything is on ext4 partitions except for the non time machine shares. Those are on a Btrfs partition.
my smb.conf is here: https://pastebin.com/JGpJB8Z1
