Muiltiple UID 0 - pros/cons and other unix superuser questions
Posted on 2008-10-07
I have seen suggestions that there be two UID 0 users, in case someone tries to log into root too many times and the account gets disabled, or to be able to change the shell and other environment variables while keeping root pristine.
I've also seen suggestions that there should NEVER be another UID 0 user, and that sudo should be used.
At this point I want to be able to log in as a superuser, use ksh, and have a home directory other than /.
I've noted that if I have another superuser created, whenever I change the password root's password will also be changed. Is that correct?
What should I do?
