Why exactly is it an issue? As long as all devices are on the same
controller (and I'd expect them to be), AFAIK there is no issue: the device
naming should be stable across reboots.
I can imagine it becoming an issue when you expect these devices to be
frequently booted with some external USB storage device connected.
Scsi chains are a specific example of the disk naming being in "as you
found it order". If you have software raid in that, and you have an
enclosure power cable incident, it gets munched.
One more good reason for persistent names.
