Process for grafting svn commits to git repo after cloning with the --no-metadata option.

graft.sh

# This assumes you prefixed all the svn branches with 'svn/' via the
# --prefix=svn/ option when you performed the initial clone. Otherwise
# replace 'svn/trunk' with the name of your branch that corresponds to
# trunk.

git svn fetch --revision [start_revision_number]:[end_revision_number]
GRAFT_PARENT_GIT=`git log --pretty=format:'%H' -1 master
GRAFT_FIRST_SVN=`git log --pretty=format:'%H' svn/trunk | tail -n` # or whatever you called your trunk
echo $GRAFT_PARENT_GIT $GRAFT_FIRST_SVN > .git/info/grafts
git checkout master
git merge svn/trunk --ff-only # I like to use fast forward only in case the master has diverged from trunk. This is optional
