Hi, Nico & Stephen:
Thanks for your reply. It is really a daunting work to build the whole thing. 
Actually, what I need to modify are linux kernel and several tools,  like e2fsprogs,
for example. After build my personal packages, how to add a yum repository 
at OS installation time? BTW, when installing the OS, how can I format  disk with
my personal tools?
