sha1 of the repo excluding history ?

    Can I obtain from git the sha1 of the total last state of the
repo excluding history ? This is a state that covers contents and
names of all files and dirs, and x perm of files;
but excludes history, timestamps, ownerhisp, and inode numbers.

That would be approximately like the slow method:
          'find | egrep -v '/\.git(/|$)' | sort | Xcpio -o | sha1sum -'
(imagining Xcpio that does not archive any ownership, timestamps,
and inode numbers). Can I obtain this result immediately from git ?
