NetBoot 499
NetBoot Desktop Admin creates a copy of the disk image. This may take several minutes, and
you should not interrupt the process. When it finishes, your NetBoot client computer
restarts automatically.
5 If you are installing a new version of the Mac OS or adding system extensions, you may need
to increase the size of the disk image.
Make sure the disk image is large enough to accommodate the size of the new system and
extensions you are installing. You cannot reduce the size of an image without reverting to a
smaller backup copy.
6 If you are installing a new application software, you may need to increase the size of the
application disk image.
Be sure the disk image has enough space for the software you want to install. However,
increase the size of an image only as much as needed. You cannot reduce the size of an
image without reverting to a smaller backup copy.
7 Install the software or make changes to the system configuration.
Make sure to install the latest updates for the system software.
If you are installing software, follow the installation instructions that came with the software.
If necessary, restart the computer.
After installing an application, open it. Doing so lets you enter a registration number, if
necessary. If you don’t enter the number now, every time users open the application they will
need to enter the registration number. In addition, most applications create a preferences file
in the System Folder. If you don’t open the application, users may not be able to open the
application because the preferences won’t exist.
8 Be sure there aren’t any files in the Trash that you want to save. (The Trash is emptied
automatically after the next step.)
Note: If you cannot empty the Trash because it contains files that are in use, you may need
to restart the computer.
9 User the Chooser, log back in to all the server volumes.
10 Open the NetBoot Desktop Admin application, then click Save. The computer restarts
automatically.
If you need to make other changes, click Quit and return to Step 7.
Important Because the copy of a disk image is associated with the NetBoot client computer
you used to create it, you must make the changes to the image using the same computer. If
you change computers, you will not be able to see the changes you have made and your
changes will not be available to users. In addition, you increase the risk of unauthorized users
making changes to the disk image.
