Re: Git as a filesystem

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

It would be just as big as the non gitified storage on disk.

The space saving with git comes from efficient delta storage of 
_versioned_ files, i.e. multiple nearly identical versions of the same 
file where the stored delta is only the small difference between the 
first full version and subsequent versions.  Unless you plan on storing 
many different Debian versions together, you won't benefit from any 
delta at all. And since Debian packages are already compressed, git 
won't be able to compress them further.

So don't waste your time.
