When you ssh over an unreliable connection and things start to lag massively when you `sudo su someseviceuser' so that you type a few times the password enter, ctrl-d because all is frozen.
And then, all of sudden your password appear in clear text in the service account shell and in your shell. So you have to clear your screen asap because of course you are on a public place when it happens. And then you have to go through the various histfiles to cover your mess... 🐵
