This is a result of an attempt to make interface names persistent by tying them to MAC addresses. It falls on its face often. There really needs to be some sort of symlink system for network interfaces so we can have multiple names for a single interface -- it would make this less likely to fail badly. >I know, >udev is seriously broken.

What "confuses your hard disks" is the asynchronous hardware probing done by the kernel. This causes disks to be detected more quickly but not always in the same order. Even before the asynchronous probing code was mainlined, /dev/[hs]d* has always been about detection order -- never a persistent name for the device that could be counted on between boot. Changing your hardware (e.g. booting with a USB stick in), kernel (changing the module link order or which modules are compiled in vs. as a module), or initrd (changing the module load order) could end up "renaming" your devices. udev allows more consistent naming. The default setup for /dev/disk/by-* gives good results for most people. >So where is /dev/eth0? Nowhere. The 2.6.x kernel does not assign a major/minor number to network interfaces.
