ok. greeeat.
so, some sensible questions:
* what _can_ be guaranteed?
* diffs?
* git-format-patches? (which i am aware can do binary files and also
rms)?
* individual files in the .git/objects directory?
and, asking perhaps some silly questions:
* why is it not guaranteed?
* under what circumstances is it not guaranteed? and, crucially, is
it necessary to care? i.e. if someone does a shallow git clone, i
couldn't give a stuff.
* is it possible to _make_ the repository guaranteed to produce
identical pack objects?
* does for example "git gc" change the object store in such a way such
that one git repo will produce a different pack-object from the same
ref? if so, can running "git gc" prior to producing the pack-objects
gurantee that the pack-objects will be the same?
* is it a versioning issue? is it because there are different
versions (2 and 3)? if so, that's ok, you just force people to use
the same pack-object versions.
etc. etc.
