Error when using the daemon option

[coaxial]

I am using guard-rails with the daemon: true option set.

It starts up fine, but when accessing localhost:3000 from the browser I am getting an error: Errno::EACCES (Permission denied @ dir_initialize - /run/runc).

Everything runs ok when not using the daemon option. I'm using a gemset with RVM if that changes anything.

Versions:

$ gem info guard guard-rails rails
