IIRC, sudo logs all commands to syslog. Which might come in handy. Yes, root commands will be logged by bash to .bash_history, but there are limits of # of commands lots, what happens if you are logged in multiple times into same account etc.
Anyway, that's why I like sudo.
At work, a relatively young engineer accidentally typed a command meant for a test database server into a production window. There was a big rush to restore from backups, and there was a small amount of data loss.
One thing that came out of the retrospective, requested by the engineer in question, was the production hat. Before you opened up a connection to a production machine, you had to put on the large pirate hat. You could only put it back when you had closed the connections. I didn't really need it, but it was a great way for people to learn the necessary caution.
It also ended up being a nice exclusive lock on futzing with production, and seeing it in use led to some good discussions that otherwise might not have happened. But the main thing was developing a strong differentiation of states in everybody's heads.
My son now definitely thinks work is like his school :-)
