To be clear, that means tools like crash, gdb, and the kernel-debuginfo package won't work at all because the information isn't part of the build. If you just want to test compiling, that's fine. If you're actively developing something and just want a faster build but need to debug issues, it might not be the best choice. > I think --without debug would be a good addition to this. Miguel, can > you send out another version of this patch with --without debug added? Yes, that is probably a good addition. josh _______________________________________________ kernel mailing list kernel@xxxxxxxxxxxxxxxxxxxxxxx https://lists.fedoraproject.org/admin/lists/kernel@xxxxxxxxxxxxxxxxxxxxxxx
