Why not just tell users to run `su $USER`?

Just curious! Instead of the reboot or log in/log out step.

Because that way you'll run commands as super user and rvm doesn't require that. And when you've joined a new group, a logout is required. There are workarounds for that, anyway.

Worked for me. Also you're wrong about what su does. The password su takes is the current account password, it only is the root password if no login name specified.

Yes, you're right, it'll basically works like a new login until you close the terminal. I never tested if it'll really load user new groups.

Yup it does :-) that's why I suggested it. It's OK, it's a weird POSIX internal thing. sudo = set user and do not superuser-do!
