+1 for that. I use LABEL=, but it's annoying that Debian's grub-install doesn't handle that (it only has options for device name or UUID).

If someone is needing to work at the device level, they they should know how to determine the device name. But from the "system doesn't randomly break itself" POV it's one way to deal with the issue.

That's the case all along. The question is how to map those node IDs to something human readable.

I would expect the system to die horribly if you do that - regardless of how you name things !
