Re: Good idea.
Why is it that sudo is used instead of su?
Several reasons. Firstly, sudo logs all its invocations. (If you use sudo -i
, that log becomes less useful). Secondly, sudo can be configured to only allow a user to run a certain subset of commands. su is an all or nothing command. Finally, su requires the destination user's password (e.g. root) whereas sudo requires the current user's password (or not at all). One benefit of this, is that when an employee leaves, you don't have to change all the root passwords, you just delete their account.
Is sudo perfect? No. As your linked article mentions, the user's password becomes the keys to the kingdom rather than a separate root password.
Know the facts and make your choice.
