I'm using git annex sync to keep the master branch of various remotes in sync. Predictably, while the synced/master branch gets synced fine, the machine running git annex sync fails to push to the remote's master branch, since it's currently checked out:

push indian
 Everything up-to-date
remote: error: refusing to update checked out branch: refs/heads/master
To ssh://indian-wired/home/adam/org
 ! [remote rejected] master -> master (branch is currently checked out)
error: failed to push some refs to 'ssh://adam@indian-wired/home/adam/org'

Is there a way to get annex sync to only try to push to the remote's synced/master and not master? I see the --no-push option, but presumably this would prevent pushing to both, which is obviously not what I want.
