Why did oldconfig switch off CONFIG_MODE_SKAS? It didn't do that before. Hmmm... Rummage, rummage... Darn it, it's position dependent. _And_ version dependent.

Ok, now I have to put the new entries at the _beginning_. Appending them doesn't work anymore, it now ignores any symbol it's already seen, so you can't easily start with allnoconfig, switch on just what you want, and expect oldconfig to do anything intelligent.

That kinda sucks. Oh well, I can have sed rip out the old symbols before I append the new ones. Here's hoping it's not _that_ position dependent...

A much better way would be to put the values in a file named:
allno.config

With latest kconfig changes this will do the trick, and you will have a valid config no matter what you put in.

Hi,

It's _not_ position dependent, but the behaviour with multiple equal symbols is undefined.

Now you can put them in allno.config instead and allnoconfig will do the right thing.

bye, Roman

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?
