It looks good in principle, but is not done correctly. support/kconfig/ is directly inherited from the kernel source code, and we keep a series of patches in support/kconfig/patches/ to clearly identify the changes we made compared to the original kernel version. See support/kconfig/README.buildroot for details. Could you rework your patch to also add a patch to support/kconfig/patches/ ? Can you check whether the problem also exists in the kernel kconfig code, and if so, report the problem to the kernel developers ? Thanks! Thomas
Hello all, This bug seems to be somewhat major to remain in the 2015.08 release, as it prevents users from using a read-only buildroot source with out-of-tree builds.

Or, will you have time to work this patch before the release according to Thomas' review? I believe it would be a very important fix, and I could pick it in case you are unable right now. Thanks, Erico
It's on my list, but I don't expect to be able to get back to this for quite a while. Sorry!

merge_config.sh currently tries to create a .tmp file in the top-level Buildroot source tree. This fails when that directory is read-only, leading to unexpected .config file contents (affecting the configuration of Buildroot itself, Linux, and Busybox). Fix it by using mktemp --tmpdir to create the .tmp file in $TMPDIR or /tmp.
