Giriş

--system seçeneği

Sistem grubu yaratır. Açıklaması şöyle

System groups are groups that are used by the system itself, such as the audio group for sound devices or the disk group for disk devices.

System groups have a number of special properties:

- They are assigned a unique group ID (GID) from a reserved range of GIDs.

- They cannot be deleted by regular users.

- They can only be modified by the system administrator.
