Hi,


I made a script that (using rsync <linux utility>) run a backup of some (particular) data of my computer.

I use an external USB-HD to store data of the backup and, of course, I need to mount this HD-device before.


A problem come because systemd-udevd automatically mount plugged USB devices when they are connected to computer.

I my “simple” mind, I fund that this automatically mounted point is”

/run/media/$USER/partition_label (...this says Gparted…).


In this way, before that I manually mount the partition in order to use the rsync command I do:

umount /run/media/$USER/partition_label.


This in OK! (this is working) ! But this is only a my empiric solution to the problem, and looking for <”linux how to manually unmounting the automatically mounted usb device by system-udevd”> I didn't find nothing exactly appropriate for my problem.


I know that are different solutions (using udev rules) to manage the automatic montage of devices, but since I already have a good script that work, I only would like find an “official instruction” for the problem to manually unmout automatically mounted USB devices by systemd-udev.


Can I have some help ?


thank you


Angelo
