Subject: make cloneconfig ?

any reason why "make cloneconfig" never made it into mainline?

many people are quite used to it and every time i build vanilla kernel i step into that trap  "oh - that`s a suse`ism"

make cloneconfig exists since /proc/config.gz - but while that one went into mainline, cloneconfig never did.

anyone know the reason for that ?

i wished, distros kernels were more similar to vanilla kernels - so what about making them more similar ?

Please consider the following patch against 2.3.10 which adds a config
option to store the kernel configuration in the kernel image and make it
available as a file in /proc. It also adds 'make cloneconfig' which will
duplicate your running kernel configuration.

Also worth noting is scripts/bin2c, which is meant to replace the poorly
named and poorly located bin2hex programs that are in various places.
