From 6439bdeb3a50aaeb1a9c431b9036c44810d9a5e3 Mon Sep 17 00:00:00 2001 From: Andrew Bartlett Date: Fri, 30 Oct 2009 15:18:42 +1100 Subject: s4:provision Split ProvisionBackend out of the main provision script This splits the code, while keeping the original behaviour. The provision.py file had become just too long.
