This is what scares me most: people running things as horrible as certbot (written by people who think it is ok to download and install a compiler without even asking before on a web server) AS ROOT.
These things have no reason to and should not be designed to run as root.
Anyway, the switch is done, but it might be good if at least one other person monitors certificate validity, if it ever goes below 20 days something went badly wrong.
