One day in '82 I was working in VM

I think I first heard the word 'Linux' around 1992 or so. Towards the end I had a sweet Lenovo W-530 with full blown RHEL and a Windows VM integrated just enough drive me nuts every couple of weeks. I've managed to stuff most of that into an old T-410 personal box running Centos, but the bitch just blew up on me this week when I tried to update to Centos 7.4 and ended up with hundreds of duplicate files for both 7.3 and 7.4 in the same instance.
