I've tried this method with Cocoon repository
(http://jukka.zitting.name/git/?p=cocoon.git;a=summary) and got this error:

git clone git://jukka.zitting.name/cocoon.git
git svn init -s https://svn.eu.apache.org/repos/asf/cocoon/
git svn rebase
Unable to determine upstream SVN information from working tree history

git --version
git version 1.6.0.2

Any idea what's wrong here?

Good suggestion.

Ah, I didn't spot this earlier. Thanks.

I see. Thanks for insightful comments.

Yep, that's true.

Agreed.

Thanks for all your valuable information. As soon as I resolve problem with git svn rebase I'll
start reading on how git am --3way works.
