Any chance that Linux package managers will integrate this for their -dbg packages? I’d rather not fiddle with downloading those along with -src, untarring it, telling GDB where to find the code…
Debuginfod does support debian packages as well (integrating with -dbg pacages), but it does not support src packages. The documentation mentions that this is tricky.
That said, debian started indexing build ids in the repos so at least for dwarf files there is a barebones index now. Sadly not for the companion executables.
