Re: Optimizing kernel-devel

After drinking yet another half a dozen cups of tea while waiting for both kernel-devel and kernel-devel-smp to install, I have an idea how to fix this mess:

1. Add one more file to kernel-devel and kernel-devel-smp packages, whose

contents are the output of:

cd $RPM_BUILD_ROOT/usr/src/kernels/<<version>> find . -type f -print | sort | xargs md5sum >../<<version>>.md5sum

2. %post would then simply read all .md5sum files, reconcile them, and know

exactly what to hard link.

I'd be surprised if this will not speed things up by at least a factor of 10.

another one would be to make a kernel-devel-base, which works for all versions, and which just has filenames that are the md5sums of all the headers. The kernel-devel package would then only contain symlinks to the md5sum filenames ;)

(yes it's a hack, and yes it's grossly horrible :)
