For various reasons of current debuginfo format + current GDB state GDB will always read the whole .debug file. Therefore it (currently) does not make a difference (in fact it would be slower) to NFS-like access it by some "debugfs" instead of downloading single .debug file. Still it may be a difference to download just specific .debug files from -debuginfo.rpm - either by "debugfs" or by some other .debug download method. OTOH that has security implications as the .debug files are not signed as the debuginfo.rpm files are, see: https://fedoraproject.org/wiki/Talk:Features/DebuginfoFS#Security This discussion is about so-called "retrace server" provided at least by Ubuntu Apport: https://wiki.kubuntu.org/Apport#Launchpad-based%20auto-retracer It has been scratch-made for ABRT but there needs to be done some more bits of work; it is currently not deployed: https://fedorahosted.org/pipermail/crash-catcher/2009-October/000052.html For the "retrace server" there comes back the question of security by possible hiding of disclosed information from user (such as hiding a password from crashed application into the backtrace to make it invisible for approval before submitting it). With current download of whole -debuginfo.rpm files signed by Fedora this security problem does not exist. There would be needed some Fedora-provided signed retrace servers with the same level of trust as have the signatures on -debuginfo.rpm files.
