I wonder if we could extend 'listnewconfig' to meet your demands instead of adding the new target. I do not know why the current listnewconfig skips choice values. (Anybody who relies on the current format of listnewconfig?) Looks like the current listnewconfig (it was 'nonint_oldconfig' before renaming) was contributed from Fedora/RedHat side. commit f0778c8c41001783d4074e34efc7d3e632d87ee3 Author: Aristeu Rozanski <aris@xxxxxxxxxx> Date: Thu May 6 12:48:34 2010 -0400 kconfig: introduce nonint_oldconfig and loose_nonint_oldconfig This patch has been around for a long time in Fedora and Red Hat Enterprise Linux kernels and it may be useful for others. The nonint_oldconfig target will fail and print the unset config options while loose_nonint_oldconfig will simply let the config option unset. They're useful in distro kernel packages where the config files are built using a combination of smaller config files. Arjan van de Ven wrote the initial nonint_config and Roland McGrath added the loose_nonint_oldconfig.
