You must assign a unique identifier to the new menu. The identifier is normally a meaningful name.
Place any title you want here. This will be displayed at the top of the menu seen by the co-administrators.
Each user defined menu creates a new privilege. The privilege grants access to the menu to a normal user. On the user accounts dialog, you'll need to grant access to the menu to anyone who is allowed to use this menu.
By default, the privilege only grants access to the menu. Any entry in the menu may define other privileges. Unless the co-administrator has those privileges, he will be prompted for the root password.
The checkbox lets you enhance the power of the privilege associated with the menu. When checked, the privilege overrides any privileges normally associated with the menu entries. Said differently, the co-administrator holding this privilege has the same power as root for the tasks showed in the menu.
Use of this checkbox must be taken very seriously. A malicious co-administrator may find a way to get more privileges (including root access perhaps). Many Linuxconf components do not define any privileges (the root password is required). This checkbox allows a normal user to administer those components.
You are presented with many checkboxes. Each one maps one Linuxconf menu entry to the newly defined menu.
You can map a terminal menu entry or a submenu. Mapping a submenu enables access to every menu entry under it.
