Starting apps on daemon start has been handed by the upstart 'dokku-redeploy' script for a while. (Also, the format of /etc/init/docker.conf changed and rendered the sed useless.)
HOME is not consistent if dokku is ran e.g. as root (for setup).
The DOKKU_ROOT variable will also make it possible to have the repositories stored in an arbitrary location (works-ish right now)
Two new hooks are implemented:
- pre-delete $APP
- post-delete $APP
The following are implemented in the `post-delete` hook:
- `$APP` directory deletion (00_dokku-standard)
- nginx reload (nginx-vhosts)
The following command can be executed by either the `dokku` or `git` user as `sudo`:
sudo /etc/init.d/nginx reload
