In fact it's quite useful to maintain several VM's of both old and new Linux releases. Sometimes you'll find an old tool or application is needed but won't run or compile on a *newer* OS. I was only able to compile Tripwire using an older compiler (conveniently present on an older RedHat OS.) VM's are cheap and having access to a variety of different OS versions can really save the day when troubleshooting app problems. Good point.
