I came here to comment basically this. Except I did it last year and accidentally broke that system. Was trying to do the working directory and mistyped and did the root dir.

For those that don’t know, so many elevated permissions commands fail if permissions are too open. And even ssh breaks because your certs and authorized_keys need to be only readable by you.

I luckily was able to wipe and just restore an older image backup.

ctrl-S instinctively from windows then panic when the terminal pauses and isnt accepting input so you restart the computer.
