Getting the Linux Kernel Config from a Running System
If you need to get the configuration of a running Linux kernel, have a look at:
/proc/config.gz
You might use that like this:
zcat /proc/config.gz > /usr/src/linux/.config
If /proc/config.gz isn't there (ie the kernel was compiled without CONFIG_IKCONFIG_PROC) have a look at:
/usr/src/linux/scripts/extract-ikconfig
