We previously assumed that systemd was detectable by the existence of certain directories. Unfortunately, it seems 14.04 already has these directories, so we need to handle this case separately.
One other note is that dokku-installer will fail to "start" if already started on certain systems, thus the previous grep was more accurate in it's running.
- Use the nginx.conf file's existence as a check for whether we should start the service or not
- Create the init files with the dokku-installer.py file. This adds actual systemd support.
- Also ensure we *always* start the service, regardless of it's status. This fixes an issue with processing systemd output
We had an issue with third party plugins installing things via apt while
already installing dokku itself via apt.
To resolve this, `plugins-install` and `plugins-install-dependencies`
now can take a `--core` flag allowing to execute the install hook only
on core plugins and not on third party plugins.
Another feature with this modification is the ability to disable/enable
plugins. Two new commands now exist:
* `plugins:enable <name>` to enable a previously disabled plugin
* `plugins:disable <name>` to disable an installed plugin. This won’t
work on core plugins.
This reverts commit 1bf30bdcb1.
Commit was reverted as this breaks installs of core plugins. It is also a hack around broken plugins that don't use the `dependencies` pluginhook.
All core plugins that require debian packages already have those packages specified in the `depends` stanza of the `control` file, so no need to respecify them here.
