I just committed dev-util/debugedit-4.4.6-r2. It requires the -r switch to rsync to be dropped to prevent copying all files in source directories. As I was looking a the prepstrip code for installsources, it struck me that it could be made much more efficient. Attached is a patch that does the following: General installsources improvements o Move the rsync run to the end so we only see errors about source files that have been moved once. Speeds up prepstrip as well. o Optimize regexp used by grep so it catches anything after the last slash that looks like: <stdin> <built-in> <internal> o Make rsync for installsources non-recursive. >=debugedit-4.4.6-r2 will now sometimes output directories. Earlier versions didn't, so the option wasn't used. This change requires that earlier versions of portage block >=debugedit-4.4.6-r2, otherwise when rsync is run, directories with all their contents will be installed in /usr/src/debug o Preserve empty directories referenced in debug sections w.r.t. https://bugzilla.redhat.com/show_bug.cgi?id=444310 o Make installsources a bit more verbose, piping up when rsync is run. This change has been tested with a full world rebuild. It makes error messages from rsync (When source files are shuffled around during the build process) much more concise and the speedup is noticeable.

Thanks, this is in svn r14706.
This is fixed in 2.1.7.2 and 2.2_rc47. I've added blockers for >=debugedit-4.4.6-r2 to earlier versions of portage.
