Gzipowanie modułów

[witekfl@poczta.onet.pl]

Gzipując moduły można zaoszczędzić kilkanaście megabajtów przestrzeni dyskowej
(w Mandrake'u - gzipują).

Tu są wstawki do macros
#-----------------------------------------------------------------
# Find and gzip all kernel modules
#
# Requires: find
#
#%no_install_post_compress_modules  1
%__spec_install_post_compress_modules { \
echo "Compress kernel modules."; \
%{!?no_install_post_compress_modules: \
    %{?verbose:set -x;} \
    find $RPM_BUILD_ROOT/lib/modules -name \*.o -print | xargs -r %{__gzip} -9nf; \
} }

# Przed        
%_source_payload        w9.gzdio
%_binary_payload        w9.bzdio

[...]
%{__spec_install_post_strip}\
%{__spec_install_post_compress_docs}\
%{__spec_install_post_compress_modules}\ # dodana linia
%{__arch_install_post}\

W załączniku patch na geninitrd.

Co wy na to?
