Diskwarrior 612/31/2023 This allows you to provide access to a fully configured system from the network. NetBoot image-A Mac booting from this image will start up to a system identical to that of the source system volume. If your system source is a nonbooted system volume, and you choose to create a. However, this combination provides the basis for building a modular system image, as covered later in this chapter. Again, when using SIU in “basic” mode this is not a very useful build combination. In other words, SIU will build a restorable system image by installing Mac OS X to a disk image based on the default installation settings. NetRestore image-A Mac booting from this image will start up to an interface allowing you to restore a generic system image based on the installation media. This allows you to provide access to the installation media from the network. NetInstall image-A Mac booting from this image will start up to an installer interface identical to that based on the installation media. This is not a very useful build combination when using SIU in “basic” mode. NetBoot image-A Mac booting from this image will start up to a fully functional, though completely generic, version of Mac OS X based on the installation media. If your system source is Mac OS X installation media, and you choose to create a. This is the deployment mechanism of choice for many because it provides the fastest method for deploying a fully configured system. The restored system image is based on either a clone of your model system or a modular system built by SIU. However, instead of performing an install of Mac OS X, it will restore a system image to the local Mac. New to Mac OS X v10.6, a NetRestore image starts up to an interface that appears to be identical to the Mac OS X Installer.The advantage to NetInstall is that you can pick and choose the individual packages that get installed, as opposed to performing a system restore, which always includes the entire contents of the system image. This is an alternative to pure system imaging techniques that restore a premade system image to the local Mac. Thus, NetInstall allows you to perform an installation of the operating system to a local Mac. In essence, you’re simply taking the original Mac OS X installation media and making it available on the network. A NetInstall image starts up to the Mac OS X Installer, much like when you start up from the Mac OS X installation media.In this case you can create a bootable Mac system, hosted on your network, that has all your favorite utilities and tools. Conversely, if a disk image volume’s contents are that of an installed and configured system, SIU will recognize the mounted volume as a nonbooted system volume.Ī popular use for NetBoot is to create an administration, maintenance, and recovery NetBoot system, for use when a Mac cannot start up from its internal volumes. Thus, if a disk image volume’s contents constitute a copy of the Mac OS X installation media, SIU will recognize the mounted volume as installation media. Additionally, SIU treats the contents of a mounted disk image identically to that of a standard volume. SIU can create network disk images of Mac OS X or Mac OS X Server from two primary sources Mac OS X installation media or any system volume that is not currently booted. Therefore, if you wish to create network disk images of previous versions of Mac OS X you must also use previous versions of the Mac OS X Server administration tools.Īs when creating a standard system image, you must have a source from which to create your network disk images. Selecting a Network Disk Image SourceĪlthough Mac OS X Server v10.6 supports hosting images with previous versions of Mac OS, the 10.6 version of SIU can only create network disk images of Mac OS X v10.6.x or Mac OS X Server v10.6.x. Further, even if you don’t intend to use the Mac OS X NetBoot service, you can still use SIU as an automated tool for creating full system images to be deployed using another mechanism. Specifically, SIU in Mac OS X v10.6 introduces a new network disk image type, NetRestore, which can be used to create and deploy system images. Though SIU is primarily designed to facilitate the NetBoot service, it’s introduced in this chapter because it’s the only Apple tool that provides an easy-to-use automated method for creating deployable system images. The Server Admin Tools v10.6 installer can be found on the Mac OS X Server installation discs, or it can be downloaded from the Apple website.
