They might, if they were used in fstab and were consistent across time and
distributions, none of which is true. I'm currently running an
assortment of
Centos3.x, Centos4.x, fedora, and a few others. By-path seems like the only

looks like it might
move if any PCI card changes, not just a matching device controller.
