2.12.2. Avoiding debuginfo File Conflicts
When you build two Software Collection packages (or a conventional RPM package and a Software Collection package) that specify the same
Source tag, and thus unpack source files into the same directory underneath the %_builddir directory, their debuginfo packages will have file conflicts. Due to these conflicts, the user will be unable to install both packages on the same system at the same time.
To avoid these file conflicts, the spec file of one of the packages has to be altered to unpack its upstream source into a uniquely named top directory. This adds one more directory level to the build tree underneath the
%_builddir directory. By doing so, the debuginfo package generation script produces debuginfo files that do not conflict with files from the other debuginfo package.
To see what the diff file comparing an original spec file with an altered spec file looks like, refer to the following example:
