- ensure nginx is always installed
- install nginx in the same way for apt-using distros
- do not install software-properties-common or python-software-properties if not needed
While I do not agree with _every_ style change, this will force Dokku to have consistent formatting across all shell scripts, which is arguably a Good Thing™.
The command used to reprocess everything is:
```shell
shfmt -l -bn -ci -i 2 -w .
```
* fix rsyslog handling
* don't hardcode dokku path
* add documentation for ArchLinux package build
* add vagrant machine to run the ArchLinux specific steps
* add step in release process for ArchLinux
* enhance docs for easy ArchLinux steps
As of 15.10, we are graced with a relatively recent version of nginx, and thus no longer need access to the ppa. Assuming this is the only such issue, this should also allow us to support Ubuntu 16.04 without any future changes.
I have done the first steps to get dokku running for other distros like
openSUSE. I have simply replaced the important places within the core
plugins with a check for DOKKU_DISTRO that gets exported by dokku
itself. It just replaces the apt-get and service start/restart/reload
functionality with the openSUSE counterparts.
