Why does rvm need sudo

The installation process is similar for both installation methods, however, when installing a multi-user. Also, you only use the sudo command during the install process. In Multi-User configurations, any operations which require sudo access must use the rvmsudo command which preserves the RVM environment and passes this on to sudo. However, please note that are very few cases where rvmsudo is required at all once the core install is completed! Updating RVM itself is not one of them.

Any user in the rvm group can update RVM, rubies, and gemsets. There is never a reason to use sudo post-install. Once any user s added to the 'rvm' group have logged out then back in to gain rvm group membership, they will be able to execute. Note: Users must log out and back in to gain rvm group membership because group memberships are only evaluated by the operating system at initial login time.
