I'm using molly-guard (htps://salsa.debian.org/debian/molly-guard, mentioned on Boulette's github btw as inspiration) since years for this after I've remotely shut down our file server thinking I was on another tmux pane. It saved me once or twice since. Btw, molly-guard doesn't require setting up aliases.

For anyone wondering how this works, molly-guard uses package diversions to actually rename the shutdown/reboot/... binaries and replace them with molly-guard: https://git.launchpad.net/ubuntu/+source/molly-guard/tree/de...

This is a cool ability of dpkg that is not well known. You can use it without making a package as well.

Didn't know what specific technique it used to do that, thanks for mentioning this!

Btw for those who wonder where the name comes from: https://news.ycombinator.com/item?id=26633320

Yes! Molly guard is genius! Unfortunately I couldn't get it to work on nixos which is not FHS-complient!
