Probably. But it may not be worth it. Why does it matter to you? Not
saying that it doesn't matter, just trying to understand why. Getting it
to be /dev/sda during install, for instance, wouldn't guarantee that it
would be that when you booted the installed kernel.
There's a seminal paper by Matt Domsch of Dell, about Linux device naming
That might give some insight. It's several years old, but pretty much
still valid, although UUIDs seem to be displacing labels for identifying
partitions for mounting. I still use labels.
