Is there a way that I can stop a
.automount without unmounting the filesystem?
I just want to prevent any future automounting, but I don't want to unmount the currently mounted filesystem.
Why can't I just remount the filesystem you ask?
Well, just as
umount --lazy is dangerous and it's impossible to know when it has completed, it seems that stopping the
.automount unit also uses the same
$ # Call this shell #1: $ # I block permissions on the unmounted mountpoint: $ ls -ld /media/backup/ dr-------- 1 root root 0 Nov 19 14:16 /media/backup/ $ ls /media/backup ls: cannot open directory '/media/backup': Permission denied # Enable the automounter: $ sudo systemctl start media-backup.automount $ # Now I can see the contents: $ ls /media/backup blockchain btrbk syncthing $ # Pin it down with a working directory: $ cd /media/backup/ # Stop the automounter: $ sudo systemctl stop media-backup.automount $ # Note there is no complaint about a mounted filesytem...
At this point in time, in another shell:
$ # Shell #2 $ ls /media/backup/ ls: cannot open directory '/media/backup/': Permission denied
So, it's unmounted when viewed from shell #2, but still accessible in Shell #1:
$ # Shell #1 $ ls blockchain btrbk syncthing
How do I stop the
.automount unit without unmounting the currently mounted filesystem?
