OK, here's where I stand now: 1. I stopped and disabled autofs. (I have 2 SMB filesystems out on the LAN that have also been automounting with autofs, do I need to do similar changes in fstab for them?) 2. yes it has. 3. none I can see. 4. nothing that leaps out at me. there are a couple about /mnt/backup not existing but they appear to be old ones, aren't happening anymore. So, I've made a minor tweak to /etc/fstab, nothing that should matter. rebooted, and when it comes up /mnt/backup is mounted. TWICE, according to the output of mount: $ mount | grep backup systemd-1 on /mnt/backup type autofs (rw,relatime,fd=25,pgrp=1,timeout=900,minproto=5,maxproto=5,direct,pipe_ino=9840) /dev/sdc1 on /mnt/backup type ext4 (rw,relatime,seclabel,stripe=8191,data=ordered) is this really a double mount, or is this what I'm supposed to be seeing? doesn't seem to timeout and auto umount.
