| |
Knowing (being sure) which configuration was used to build a (maybe running) kernel is important for many scenarios.
It's usually much more important than saving a few kb in the size of the kernel. Therefor turn on CONFIG_IKCONFIG and CONFIG_IKCONFIG_PROC by default and make them visible only when CONFIG_EMBEDDED is enabled, preventing premature optimization.
Because I just have seen too many systems where the used config got lost and people were unable to rebuild an updated kernel, I finally prepared this patch. IKCONFIG is already enabled in most distributions and embedded kernels.
