I have read his page, quite informative.

set-tree is needed for starting a SVN tree from a git tree, I don't
know of any other way to do that. I got both linux and u-boot
git trees in which I do custom mods. I then use git-svn 
to maintain a svn tree which I start with set-tree to commit
the initial tree, then I dcommit my local mods. 

Maybe maybe an option to git-svn init/clone where you can specify the git
parent for a certain svn revision?

git rebase is a bit annoying as you loose the old tree if you don't take precations.
Also, I am not sure what will be committed to SVN if I rebase my local mods on top
of linus latest.
