james.page@ubuntu.com 2014-05-01 Bump ulimit for rabbitmq to support loads of connections
  Jorge Niedbalski R. 2014-06-11 - Increase default ulimit to something more scalable using /etc/...
Switch back to correct way of setting limits for server processes
Resync with precise charm
Add publish target to makefile to help prevent precise/trusty branches getting out of sync
Fixup lint
[james-page,r=gnuoy]

1) resync with precise version of this charm - they should be one and the same

2) add target to Makefile - publish - which pushes to both charms

3) revert the changes to how open file ulimit is changed - pam is not effective for server processes.
