Beyond that, allno doesn't come close to switching everything off. 1) You have to _enable_ CONFIG_EMBEDDED in order to go into that menu and switch _off_ the stuff in there. 2) The stuff CONFIG_EMBEDDED reveals isn't all in that menu. CONFIG_BLOCK is at the top level menu. CONFIG_VT and CONFIG_UNIX98_PTYS are buried down under device drivers->character devices, and there's more sprinkled all over. You have to track it all down and switch it off to get an _actual_ allnoconfig kernel. (I cut the bit where you reinvent miniconfig. People keep doing this. I dig it up and resubmit it every year or so, so Roman Zippel can shoot it down again. Meanwhile, not only is Firmware Linux happily using it, but I even wrote more documentation at http://landley.net/code/firmware/new_platform.html although you have to scroll down a bit to get to the stuff about miniconfig...)
