BTW. We do now remove the relocations against .debug_* sections in Fedora (using rpm >= 4.9 and elfutils >= 0.153) and that saves a lot of space: http://lists.fedoraproject.org/pipermail/kernel/2012-February/003665.html "This saves ~500MB on the installed size of the kernel-debuginfo package and makes the rpm file ~30MB smaller" Cheers, Mark
