I have an asus motherboard where either the motherboard doesn't
apply a ranking to the ports or Fedora ignores the ranking. I have
an SSD (which has Windows drive C, Fedora Boot and Ubuntu Boot on
it) and 4 3TB hdd's, with the SSD plugged into port 1 on the
motherboard and the hdd's plugged into ports 3 - 6. When Fedora
starts up it sees the SSD as /dev/sdc, two of the hdd's as /dev/sda
and /dev/sdb and the other two as /dev/sdd and /dev/sde.
Is this something you want to solve, or just a point of interest?
With some motherboards, the BIOS boot order seems to rearrange what it
thinks of the hardware, and there's various parts in my UEFI where
I can rearrange how it considers the drives. Leading to some
shenanigans to get it to do what I want - act in a logical manner. It
has a separate drive order list, and a separate boot priority list.
Logically speaking, if you skip a port (you're using 1, 3, 4, 5, 6),
/dev/sdb could be overlooked, or applied to the drive in the 3rd port,
if a board enumerated the ports in sequence.
Some just look for bootable code where you tell it to look.
The old GRUB made your boot drive hd0, but I think that only mattered
to itself. The new GRUB is nightmare to deal with.
The reordering shouldn't matter to anything. Both the OS and grub
default to using UUIDs for everything instead of specific device names.
