no, I was suggesting a pack file that contained _only_ the head version.
within the pack file it would delta against other files in the pack (how many
copies of the GPLv2 text exist across all files for example)
however Willy did a test and found that the resulting pack was significantly
larger then a .tgz. I don't know what options he used, so while there's some
chance that being more agressive in looking for deltas would result in an
improvement, the difference to make up is fairly significant.

Subject: Re: Smaller compressed kernel source tarballs?
It sounded like you were talking about a modified pack file that did NOT
contain everything you need to get the current source. You said it would
have no history and use aggressive delta compression to achieve a smaller
size than a full tarball. If the pack contains the full previous version and
the delta to the head version, then it will be larger than the tar, not
smaller.

I just had what's probably a silly thought.
as an alturnative to useing tar, what about useing a git pack?
create a git archive with no history, just the current files, and then
pack it with agressive delta options.
Isn't that what a patch.gz is? Diff generates the deltas and then they
are compressed. Can't get much simpler or better than that.
not quite, a git pack includes everythign you need to get the full source,
a patch.gz requires that you have the prior version of the source to start
with.
