It looks like the current build does a lot redundant extra work that might be prevented if rpm provided better hooks to do automagically what the kernel spec build requires. One thing rpm wants to introduce in the future (already upstream) is parallel processing of debug files. Which the current kernel.spec seems to prevent because it serializes the processing itself already. > > I would be happy to review any feedback on why the kernel.spec has the current hacks and suggestions for improvements to make this smoother. > > Cheers, > > Mark I spent some time looking at this and I have something that produces debuginfo without overriding find-debuginfo.sh or calling debugedit manually. I have no idea if this debuginfo is useful/correct so this needs more review/testing. Patch is attached if anyone wants to review and there is a scratch build going at https://koji.fedoraproject.org/koji/taskinfo?taskID=18701457. One area that could really use improvement is the filtering. The kernel filters everything into many different debuginfo packages using the -p filter. Debugging those regexes is an absolute nightmare and my current proposal relies on knowing how find-debuginfo.sh sets the build-id. Do you have any suggestions on how to make the filtering more sustainable? Thanks, Laura
