I just want a minimally expressed config. I've jumped through a number of
hoops trying to get "allnoconfig plus these symbols" to work.
Setting .config to my symbol list and doing old config prompts a lot, doing
yes "" | oldconfig sets lots of crap by default (since not all default values
are n), and doing yes "n" | oldconfig goes into an endless loop every time
it's prompting for a number or some such. You have to start with
allnoconfig. Appending the new symbols and re-running oldconfig worked for a
number of versions, until now. Now you have to insert the new symbols at the
beginning.
I could presumably also work around the new breakage via following allnoconfig
with a sed -i invocation to remove the appropriate "# blah is not set" lines
before appending the symbols. (Of course it means that the config symbol
list has to be fed into a for loop instead of being expressed in the same
format as config, which sucks deeply. Insert at the beginning works until it
changes again...)

Testing...
Ok, that worked. Weird and totally unituitive name for a miniconfig, but oh
well.
Is this documented anywhere?
