I have read your mail about minimal image posted on Feb 19 on this mail list. We try to reduce image size by what your said:

eglic configurability

using mklibs

Right now after migrate eglic configurability to my local yocto branch, and I only enable 4 options ("locale-code nsswitch rtld-debug posix-clang-wchar ", pls. check in attachment) of eglibc just to make compile pass.

When after create minimal image, the rootfs (tar.bz2) is still about 3.4M, same size as without adding configurability to eglibc.

Could you give me some directions what should we do in next step? We also hope some information about how to use mklibs to reduce packages and image size?

After open MKLIBS_OPTIMIZED_IMAGES ?= "core-image-minimal" in local.conf, the minimal image decrease from 3.4M to 3.1M, after extraction is 8.1M( vs. 8.4M before using mklibs). It looks like not so efficient as we expected.

Should I try to reduce busybox size at same time?Such as remove some not so usually used commands by configurations?

Any suggestion or guild will be appreciate!

Thanks and Regards,
Kai
