[systemd-devel] udev rule to mount ext4 with data=journal

[Pascal K]

I try to achieve that regardless the device plugged to my embedded system
the mount will be in folder /media/"name_of_volume".

If I understand correctly for the usage of fstab I have to give a static
name for the mount point.

Thanks for pointing out the "nofail" option.

Best regards,
Pascal
