1. Because NetBoot unifies and centralizes the system software that NetBoot clients use,
software configuration and maintenance is reduced to a minimum. A single change to
a NetBoot image propagates to all client computers on the next startup. NetBoot also
decouples the system software from the computer, decreasing potential time invested
in software troubleshooting.
2. A client must have selected a network disk image via the Startup pane within System
Preferences, or the user must hold down the N key at startup to boot from the default
NetBoot image, or use Remote Desktop Admin.
3. NetBoot makes use of DHCP, TFTP, NFS, and HTTP during the NetBoot client
startup sequence. DHCP provides the IP address, TFTP delivers the boot ROM
(“booter”) file, and NFS or HTTP is used to deliver the network disk image.
4. Because the NetBoot boot image is read-only, anything that the client computer
writes to the volume is cached in the shadow file. This allows a user to make changes
to the boot volume, including setting preferences and storing files; however, when the
computer is restarted, all changes are erased.
