You can either make a minimized configuration by hand, or you can use my shrinker script (which is slow, but can be left running in a background window). I've attached the script. For ARCH=um, you'd cd to your linux source directory that has the .config you want, and run it like: ARCH=um ./miniconfig.sh mini.conf And it should produce a file "mini.conf" when it's done. The progress indicator shows two numbers (111/222) which are the number of lines it's confirmed it needs to keep, and the total number of lines remaining in the file. The one of the left counts up, the one on the right counts down, when they match, it's done. Doing a better version of this in C as a patch to the kconfig infrastructure has been a todo item of mine for over two years. :( > You can trigger the bug here by > changing "Enable loadable module support. UML supports modules? Huh. (Yeah, I suppose it does. I've never used it.) So the bug is "module support doesn't compile in UML 2.6.21" then. Might want to change the title and resubmit. :) Rob
