As part of the Node-RED 1.0 release we have expanded our Linux install scripts to include RPM based distros like RedHat, Fedora and Centos. We have moved the scripts to a new github project called Linux Installers.
Of course the Debian based installer for Raspbian, Ubuntu, et al is there as well. This means that from now on we will be updating docs to point links to this new location, and that users should use this in preference. The old Raspbian focussed project will remain there to catch any "old" links that point to it - and the script should continue to work but will add a banner suggesting users start using the newer script.
Naturally we would be happy to look at pull requests to expand this to other Linux flavours if anyone is feeling generous.
As with all web based scripts we would advise users to have a look at the script to satisfy themselves we would do no harm in their environment.
