this one?

seems what I need..

in this case, I had a question:

since if I use this feature my commit will have different SHA-1. I
used to write the commit SHA-1 in some of the svn tags. If I do this
they will no longer be valid.
I think with git SVN the "best" way to identify a commit is using the
"Tree" object SHA-1, it should be the same for every revision that
contains the same content...
so..
1b. Can I extract the tree sha-1 from a commit?
1c. Is there a way to get every commit pointing to to a tree?

Ideally I would do something like

git contain-tree <sha-1-of-the-tree>
[list of commit's here]

does this make any sense to you?

Renamed, thanks.
do you know if I can set a GIT_SVN_ID (default) per-repository instead
of using the environment
variable?
(since I use git-new-workdir it would be best if I can use a default
per workdir)

thanks, did it.

no,
what I had in mind was a "migration team" to work on the migration of
the customization
to a product to the new version of the main product.

What I have in mind here is some kind of "selective merge".
For example...

I merge a group of commits, someone else, on another computer with
git-svn or subversion merge another part and so on..

like...

git merge --squash -- path/to/something
or something like

git merge --squash --interactive

this could give you a way to choose different paths you want to "merge".

I know this is not very like a merge but I hope I gave you the idea of
what I meant.
