deploy:force_unlock

Removes the deploy lock file. If a deploy is terminated midway, it may leave a lock file to signal that deploys shouldn’t be made. This forces the removal of that lock file.

$ mina deploy
-----> ERROR: another deployment is ongoing.
       Delete the lock file to continue.

$ mina deploy:force_unlock
-----> Unlocking
       $ rm /var/www/kickstack.me/deploy.lock

$ mina deploy
# ...The deploy should proceed now

This may be invoked in the command line or as a subtask.
