Re: Git as a filesystem

quoted

I wonder how big a deltified Debian mirror in one pack file would
be. :)

Very, very close to 252 GB, since .deb files are already compressed.

Yes, but if there were deb and tar support in git (to automatically unpack
archives and store the contents), together with the best available
binary diffs I think the repository could be significantly smaller because
files common to all architectures could be deltified,

I did a quick check with 100MB of deb archives; the result was nearly 100MB
as you said.
I also did a quick check with all .so files in my /usr/lib directory; it shrunk
from 50MB to 20MB, the same is achieved with tar + bz2.

But the thing is, I think there is a lot of redundancy in
a) a Debian mirror or
b) your disk at home.

Telling git to handle -for example- deb archives and storing
everything in a pack file would take advantage of redundancy across
_all_ files.
So the /usr/share/doc of all architectures could be compressed.

Right?
