In-Depth Information
Because these four daemons are required to support over-the-network installation
(with or without JumpStart), the
add_install_client
will configure and start the
daemons (on the install/boot server) if required when a network install client is
configured.
Automating Installation with
JumpStart
The JumpStart feature provides a mechanism to automatically install the
Solaris operating system. The two JumpStart methods are JumpStart and
Custom JumpStart.
Not only does JumpStart automate installation, it can be used to automate the instal-
lation of large numbers of systems that are identically configured. If you need to
install hundreds of systems using the same configuration, JumpStart provides a way
to simplify this task.
JumpStart enables automatic installation of the Solaris operating system on
new SPARC platforms by inserting the Solaris distribution CD into the local
CD-ROM drive and powering on the system or booting via the network.
The software that is installed is determined by a default profile. The default
profile is selected based on the hardware model, RAM, and the size of the
hard disks. The software installed cannot be manually selected.
All new SPARC platforms have a preinstalled JumpStart boot image. This
boot image can be copied to an existing SPARC platform by using the
re-preinstall(1M)
command.
Custom JumpStart enables automatic installation of the Solaris operating
system on new SPARC or Intel x86 platforms by inserting the Solaris distri-
bution CD into the local CD-ROM drive and powering on the system or
booting via the network. The software that is installed is determined by a
custom profile. This provides a method to automatically install groups of
systems in an identical manner. The custom profile, along with other
JumpStart configuration files, is located in the JumpStart configuration
directory.
JumpStart Configuration Directory
The JumpStart configuration directory contains the files used to customize a
JumpStart installation. It provides a way to automate the system configura-
tion phase of an installation for groups of similar systems. This directory can
