[Server-devel] XO Visualization Feature

Wed Jun 4 09:26:08 EDT 2014

Hi Martin,

I should point out that while I got it to install eventually, the first
fail on the "add admin user" is a common problem I noticed across multiple
installs..

The goes like this.
./runansible
... fails at add admin user
./runansible (again)
....goes past the step just fine, and install works as expected.

I have limited bandwidth this week to debug why this is happening, so it
would be great if you could also maybe look into it.

Thanks,
Anish
