Package reduction(package minimisation) for minimal rootfs

Dear All,

                I have task to minimize the root file system, by removing busy box and adding additional packages in place of busybox like core-utils, binutils, tiny-login etc.

                I have tried some of the approach of trimming rootfs and poky tiny version.

                Additional packages greatly increased my rootfs size.

                Please clarify my doubts,


1.       Is it possible to remove un-necessary files/executebls/libraries from the package, if so kindly guide me in minimization.



2.       Can I change the do_config in recipe of the package to customize the contents of the package?




3.       Is there any possibility I can control which all files to added to the rootfs from do_rootfs or any other configuration.



4.       For this kind requirement is own custom distribution a good approach?

Please guide me in this.

Thanks a lot in advance.

Thanks and regards

The following quotes are taken from http://busybox.net/about.html:

    "BusyBox combines tiny versions of many common UNIX utilities into a
    single small executable. It provides replacements for most of the
    utilities you usually find in GNU fileutils, shellutils, etc."

    "BusyBox has been written with size-optimization and limited
    resources in mind."


In general, if you are trying to make a small system you would remote 
things like core-utils and replace them with busybox, not the other way 
around.

Maybe having a look at poky-tiny might help?
