Okay let me re-qualify the statement: "If my desktop only has one Ethernet interface, and I don't mess up with it in userspace at all, no matter how many kernel changes happen, it'll always be eth0". Yes, the previous persistent rules for udev would have messed that one up when e1000e got split, or if you switched between the Broadcom-provided driver to the kernel one or vice-versa. The deathforce drivers come in mind as well. > >> > Whereas, with the new predictable scheme, if I move that card around, it >> > will change name. > It's even worse, if you mess with kernel parameters (esp. pci=assign-busses > for PCMCIA) then the device numbering might change without hardware moving > around. Sweet I didn't think about that. Yai for predictably variable names. -- Diego Elio Pettenò — Flameeyes [email protected] — http://blog.flameeyes.eu/
