So it is advised to use persistent identifiers such as UUID or LABEL instead.Yes, what you say is true, but not very often and from what I've seen is due to mainboard setup or defects in the mainboard causing the bad setup due to mainboard SATA connection being mislabeled.
No, it is due to the asynchronous nature of device probing and module loading by the kernel and udev in modern Linux systems.
But if everything is correct and you are using lets say sda1 as root in your fstab your system will use sda1 as the LABEL, I've seen this over and over.
Nonsense. sda1 is the block device name and does not have anything to do with the LABEL which is a filesystem metadata field.
But all this is advanced setup for people running more than one Linux system and having to edit UUID on all systems because you install a new system is undesirable.
No it does not have anything to do with multiple Linux systems.
