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.
