My big whoops was remotely bricking a server on top of Mt Haleakala. I needed to update MySQL to take advantage of some new feature that young, eager me just _needed_ to use. Well, the package repo didn't have that version, so no worries, I'll install from source. Well that required some newer version of a core utility, so no worries, I'll just `yum update` that. No dice. No worries, I'll just force remove and install the newer one. Well, young, eager me didn't realize essentially every command relied on that core utility, so although I had a prompt, I couldn't even `ls`, much less `yum install`. Our site technician had to take an OS disk up with him next time he made the 2+ hour drive to the top. Luckily we did have a KVM set up so it didn't require a site visit from me (or is that unlucky...it would have been a trip to Maui!).
