Detailed Description
New work in elfutils will provide facilities for DWARF compression. The conventions for finding separate debuginfo files might be enhanced or rejiggered in tools like gdb and systemtap. The rpmbuild macros and scripts for generating debuginfo packages will be rewritten. These are expected to make the debuginfo rpms much smaller.
Possibly the standard will change to split debuginfo packages into debuginfo proper (/usr/lib/debug files) and sources (/usr/src/debug files) as separate subpackages.
Benefit to Fedora
Much smaller debuginfo rpms, quicker to download, smaller to host/mirror, etc.
Scope
elfutils team has to write the DWARF compression tools (will also replace rpm's debugedit), come up with debuginfo convention changes.
elfutils team + rpm/redhat-rpm-config maintainers have to decide about subpackage conventions and implement new macros/script to replace rpmbuild find-debuginfo.sh magic.
Either gdb team has to adapt it to new conventions, or DWARF tool + rpm deployment plan could include exploding in %post to current layout.
If rpm subpackage convention changes, possibly rel-eng needs to adjust mash for new naming convention and multiple debuginfo-related rpms per package.
How To Test
User Experience
Quicker to download and install debuginfo rpms.
Dependencies
elfutils work.
Might like a mass rebuild to get all new debuginfo rpms for the release.
Contingency Plan
We can punt the whole thing.
We can do it but skip the mass rebuild.
We can punt adapting gdb et al if we do a deployment scheme that explodes to compatible old data in %post.
Documentation

Release Notes
Should have some notes about conventions and tools when decided.
