This is +necessary on systems where the BIOS name for a given device (e.g. the +label on the chassis is "Gb1") doesn't map directly and obviously to +the kernel name (e.g. eth0). + +The distro-patches/sles10/ directory contains a patch needed to +integrate biosdevname into the SLES10 udev ethernet naming rules. + +This also works as a straight udev rule. On RHEL4, that looks like: + +KERNEL=="eth*", ACTION=="add", PROGRAM="/sbin/biosdevname -i %k", NAME="%c" + + +This makes use of various BIOS-provided tables: + +PCI Confuration Space +PCI IRQ Routing Table ($PIR) +PCMCIA Card Information Structure +SMBIOS 2.6 Type 9, Type 41, and HP OEM-specific types + +therefore it's likely that this will only work well on architectures +that provide such information in their BIOS. -- cgit v1.2.3
