Sure, but not as long as calling SCSI drives sd? and keeping them the
same until the hardware changes. It seems silly to rename things every
reboot. And, IIRC, udev was supposed to do away with the need for
So if you put a new disk in a box, how do you find its name to
partition/label it? Yeah, you can look at the /dev/disk/by-* links (as
long as you don't have two of the same kind of disk). Still seems silly
to me not to have a useful default for simple cases where you don't want
to have to pick a name yourself.
I updated my rules to make my drives sataa, satab, and usba. Well, the
USB drive gets renamed just fine (it matches on product since I have
more than one but they get named the same). The SATA drives show up as
sda and sdb--matching on serial isn't working for them. That's fine
until one of them shows up as sdc (the USB starting as sda and then
getting renamed). I'd like to think that won't happen but that's what I
thought before I started down this rabbit hole.
