Restrict su command

I have user1 and user2. Normally, the user root can switch on all users with su command.

I want to restrict su command so that the user root can switch only to user1. It is possible??

Nope. Root is root, and can do all and see all.

no way you can restrict access to root but you can restrict su to all users/groups – ostendali Oct 09 '15 at 09:34

As womble already said, you can't restrict access to su for root, since it could just change whatever you use to restrict su with, anyways.

If you want to restrict su in order to stop root from reading your personal files you could encrypt them (or your whole home directory).
