I got into this bad habit of trompsing around as root on our dev systems at work because who gives a shit we abuse and reprovision those systems all the time.
But then I find myself at home on one of my home servers or desktops fumbling around as root. Because I don’t want to constantly run sudo. Fortunately nothing bad has happened, bad enough to be memorable anyway, in the last 20 years or so. I guess I’m still pretty careful. Or lucky.
