Failed at what? I want my sysadmins to have full access, I just want to know what they did. I'm not trying to defend against malicious staff members - I trust them, otherwise they wouldn't have sudo access.
The idea for sudoedit is that it allows you to allow non-root users to safely edit files, and if they shell out of their editor then they've not gained root rights - they edit a temporary file as a regular user and then sudo moves the file into place after it is edited.
