Running pi_piper in Rails about pi_piper HOT 3 CLOSED

Hi,
PiPiper needs root permission to work, it access to /dev/mem (via a kernel module or directly wih the C library) which need root permission.

As it is not advised to run a webserver as root, I will recommend you to escalate permissions only for a PiPiper dedicated process, there is an issue about it, but nothing as been properly written as of now.

If you make any progress on this front keep us up to date.

I'm not going to say it's the best idea performance becomes an issue when running the full rails stack but ... This is a site I wrote to do LED stuff: https://github.com/bguest/blinky... If you look at the pusher_example branch its pretty basic. Also, yeah, you need to deploy to root.
Also, here's a write up on how to set up the pi: http://www.blogithub.com/bguest/pi_on_rails ...

So after much trial and error I end up installing everything as root. I could not get rails to write to GPIO pins with out installing ruby, rails, pi piper all as root. It works, but there has to be a better way other than installing as root.
