From a79c0038ae84c38fe063bd7426a839f3c01c10e8 Mon Sep 17 00:00:00 2001 From: Allan McRae Date: Thu, 1 Sep 2016 16:37:50 +1000 Subject: [RFC] Provide source files for useful debug packages Debug packages are fairly useless currently because the soucre files needed for stepping through code etc are not packaged with them. This patch adds the needed source files to the debug package and adjusts the debug info to look at the /usr/src/debug/ directory for them rather than the build location. This requires using the "debugedit" program which is provided as part of the RPM sources.
