Just to follow up on this because I think it's interesting =)
One possible utopian future is thus:
o Modify Koji to create profile-gathering versions of some targeted
applications like Firefox; this would be a separate repository with
packages of the same name
o Have a yum plugin that allows you to replace your installed packages
with the profiler-compiled packages
o When you enable this plugin, Hotspot also goes into "dump profile
information" mode
o A new Fedora server where people can post the data from their profiled
packages and Hotspot logs
o Teach Koji to pull the data from this server and compile the software
using it
Make sure you flag down some of the koji authors with this idea -- koji
will need to grow a method of snapshoting the profiled data when it does
a build otherwise it won't be able to satisfy its mission of creating a
precisely auditable build.
