If I switch to the predefined user 'rails' and try to run 'rails console' it gives me this permission error:

/usr/local/rvm/rubies/ruby-2.2.1/lib/ruby/2.2.0/fileutils.rb:252:in `mkdir': Permission denied @ dirsmkdir - /run/user/0/spring-1000 (Errno::EACCES)

if I try to log in as root it tells me that it can't authenticate with the database. I get that; the environment variable is only set for the Rails user.

Am I not missing something or does this seem like a flaw in the design?
