Open Stack

 Hello again!

 Now i am trying to add Ironic-driven compute note to existing devstack. Below is my local.conf for it. When i run stack.sh, it does
something, then starts to reinitialize projects, users, groups, tenants, etc, effectively destroying my existing configuration.
After that it dies with "cannot connect to... something", and my system is in non-working state, ready for reinstalling from
scratch.
 Actually, two questions:
1. Is it possible to tell stack.sh to keep old configuration? Rebuilding it every time is very tedious task.
2. Why does my compute node wipe everything out? Because i enable 'key' (keystone ?) service? But ironic forces me to do it ("key"
service is required by ironic). So how do i install the thing correctly ?
