I thought about virtual partitions but if the primary linux stuffs up, 
everything is lost, If I were going this path I would use CentOS as the 
primary.

I wanted ubuntu and fedora to be quite separate but did not realise 
that  upgrading ubuntu from 12.10 to 130.4 would trash the grub that I 
was using.
