the idea was to use a git pack instead of a .tgz or .tar.bz2 as a distribution format from kernel.org
for example, the pack would only include the 2.6.18 kernel, no history.
once git supports shallow clones then the distributed blob could be a clone seed that a person could download and then track changes from there forward. but that's a future enhancement.
