Case in point: Over the next six weeks, we will see big new releases of Ubuntu (13.10), openSUSE (13.1) and Fedora (20).
Do I absolutely need to install each of them? No. Of course not.
Will I? You bet your bottom I will. As well as the Beta versions, and some of the more intriguing re-spins and child distros.
All of which means that my testing box will be wiped clean and re-loaded with a different base system every three to four days. That’s barely enough time to install all the software I want to test, configure things just how I like them and update from the repository a few times… before it becomes time to completely erase my masterpiece and repartition the drive for the next adventure.
