Re: t's best to try them on a test machine before allowing them anywhere near production
I do that too. They are pleasure to work with because they boot really quickly so testing is simple, let me build the updates myself (if I wish to) and the license is not only free, they also let me see and tinker with the sources or build options.
Oh ... but that gives the game away, doesn't it? It's all Linux. Smug, me?
