Hello, I can't say I'm negative toward CentOS, I used it back in the late 90s (? Maybe early 00s), as an alternative to RedHat at that time. It's more a familiarity thing. I have used more Debian based Linux distros since the mid 1990s than anything else. I will certainly look into CentOS as an option. Could be a shorter path to completion. Thanks for reminding of that as an alternative. My friend just toured Fermi Lab and brought me back a lapel pin. I was thankful but very envious of her visit there. It's certainly on my list. I could probably just retire and, quite happily, tour all the worlds particle accelerator facilities. Make a nice scrapbook of blueprints.
