Making simple rootfs using ELDK

ELDK ramdisk is really small and the ELDK pacakages includes almost all of the utils.
You do not need to navigate web and try to searching source code for SW pacakges
Basically root file system packages are included in PSP but that also includes something that we do not need and it makes increase flash image size and sometime it spends useless time for boot.

If you are using ELDK rootfs and just exchange libs and binaries, you can get optimized filesystem for your own. Then add packages what you need.
