The kernel doesn't appear to create the networking interfaces, though. CONFIG_DEVTMPFS is only going to handle things that physically exist within /dev, of which, ethernet devices have always been excluded. If that can get fixed in some fashion, then devtmpfs pretty much does make this a non-issue.

initramfs was introduced in 2.6.10, and prior to that, only a handful of architectures even supported a built-in initrd (MIPS was one, and it wasn't very pretty or functional). I believe other distros required the bootloader to pass the initrd to them somehow, but having never used an initrd in that fashion, I don't know for certain. But yes, if you enable CONFIG_IKCONFIG_PROC, you're essentially turning on (or utilizing) an initramfs accessible via /proc. -- Joshua Kinard Gentoo/MIPS kumba@g.o 4096R/D25D95E3 2011-03-28 "The past tempts us, the present confuses us, the future frightens us.
