Clone a repo with selected branches + git worktree layout

1. Create the directory for git worktrees:

    mkdir repo_name
    cd repo_name
   

2. Init a repo:

    git svn init https://path/to/svn/repo_name --username=<username> --trunk=branches/main_branch main_branch
   

3. Edit repo_name/main_branch/.git/config so that it contains something like:

   [svn-remote "svn"]
     url = "https://path/to/svn/repo_name"
     fetch = "branches/main_branch:refs/remotes/svn/main_branch"

   Add more fetch keys to fetch more branches

4. Inspect the SVN log to find a first revision:

    svn log https://path/to/svn/repo_name -l <max-depth>
   

5. Fetch that revision:

    git svn fetch -r<revision>
   

6. Fetch all newer revisions:

    git svn fetch
   

Re-create the git-svn history from an older revision

1. Delete .git/refs/remotes/svn.
2. Delete .git/svn
3. Run git svn fetch -r<revision>.
4. Run git svn fetch.
5. Rebase local branches.
