Pinguy Scripting

Greetings!
First I wanted to thank the developers and contributors to Pinguy OS and Pinguy Builder for all their hard work.

I have two questions that may have been answered in a previous thread:
First, is there a way to specify the version the ubiqiuti installer uses? I'm assuming it pulls from lsb_release?

Is it possible to have a PinguyBuilder built system run a specific script on it's first boot?

Thank you!
