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

22 initramfs was introduced in 2.6.10, and prior to that, only a handful of
23 architectures even supported a built-in initrd (MIPS was one, and it wasn't
24 very pretty or functional). I believe other distros required the bootloader
25 to pass the initrd to them somehow, but having never used an initrd in that
26 fashion, I don't know for certain.
28 But yes, if you enable CONFIG_IKCONFIG_PROC, you're essentially turning on
29 (or utilizing) an initramfs accessible via /proc.
