How to effectively set user permissions in Gaia OS
The Gaia operating system has a granular Role Based Administration (RBA) system.
Each administrator managing the Gaia OS should have his own user account. This user account should be assigned with a Gaia OS role, granting the appropriate permissions to Gaia OS features.
The Gaia pre-defined 'admin' account is assigned with the 'adminRole', which grants full permissions to all features. The 'admin' account should be used by the most privileged administrator since it has ultimate control over the machine.
There are several Gaia OS 'power features', which provide a user (who is permitted to use them via an assigned role) with a privilege level equivalent to that of 'adminRole'.

Setting expert mode access permissions in Gaia OS
