Trimming uclibc in l4

Dear all,

I would like to extract the minimal subset of uclibc required by bootstrap, sigma and their dependencies only. My idea is to have these modules use the smaller libc while retain the usual uclibc build for the other packages. 

I intend to go about this by copying uclibc (say into uclibc_min) and then modifying the contrib_files_all.lst and contrib_files_x86.lst. Is this the correct way to do this?

Also, I extracted all the package dependencies of bootstrap and sigma from the control files (below)

bootstrap: drivers_uart drivers_of libc l4util cxx_io
drivers-frst:libc
l4util: crtn libc
crtn: l4sys
l4sys: ldscripts
l4util: crtn libc
cxx: l4sys l4util
ulibc: l4sys
sigma0: crtn l4sys l4util libsigma0 cxx_io
libsigma0:  l4sys


Is this the correct way to do this as well?

Thanks,
Ramya
