thank you for taking care of it.
I'm still lost about who's responsible of the probing/scanning of the storage devices at boot. Is the fstab's creation imply this, or the kernel will do it anyway, or the udev rules, or..? ( I didn't know much about udev rules writing/reading, I've made a little research to understand more before coming back to you, I've come to notice that in the '/etc/.../98-tc.rules' a rebuildfstab is done for add/remove actions on block devices - but full stop for me after this info!).
By the way, my question is related to another topic: 'howto make my unique flash key my working computer (using other computers as dummy hosts)?' that's why I don't need to touch -at all- any other storage device on the hosts.
