You cant have everything. How do you describe a filesystem to mount:
Its either the location, then the content may change, or it is the
content, then the location can change (content in the sense of fs UUID).
And in the case of pci cards, there is no need for PCI hotplug. Just
open your PC and move the SCSI card from slot a to slot b. result:
device node doesnt match if you go for location.
