Yes. You can create the 'initial' tag with

  git rev-list HEAD | tail -n1 | xargs git tag initial

and from then on

  git describe --tags --match initial | cut -d'-' -f2

will give you the increasing "revision" number you're looking for. Just be aware that if you have two parallel branches with the same number of commits, they will give you the same number. I.e. this only works for a single, stable (i.e. no history rewrites), branch of development.

Hope this helps,
