NPIV won't solve clone customization. It just solves perfect access
control. Your boot from the un-customized clone disk would fail with
perfect access control because of access denied.
Well no second thought there's indeed more to NPIV: You could use zfcp
automatic LUN scan, to get rid of a lot of places where a Linux disk
image contains path information (target WWPN, FCP LUN) that would
otherwise need to be changed as part of disk clone customization.
I suppose friends of disk clone provisioning also try to avoid any use
of identifiers that change for a cloned disk, e.g. don't hardcode WWIDs
in multipath.conf or elsewhere.
But all that's only part of still necessary further customization.
