RHEL 6 workstation in Palm Beach, FL.
Had yum update run in order to grab the new Firefox.
Something happened. Something horrible.
Kernel panic on reboot. Had to choose prior kernel to start. Weird behavior all around. Yum had duplicated 960 packages. Two different versions of our own software were installed. A cleandupes operation deleted 2 gigs of stuff. It also, somehow, set SELinux to strict enforcing. System lost all connectivity save the ssh session I had open.
Long story short, I'm going to have to manually verify that nearly 1000 packages are correctly installed and are the proper versions.
If this box were to be rebooted right now, it would never come up again.
So.. How has your day been?
