7.3 SunOS 5.X

7.3.8 JumpStart

JumpStart, or auto-install, is designed to make the installation easy and automatic. This allows you to pre-configure the information you need to do the install. It also allows you to readily install many machines with the same configuration, rather than having to worry about each of them individually. You make a stub on the disk containing the information about the packages you want to install. On the NIS(+) server you can configure the network information for the new system including the hostname, IP address, time zone and domain name.

If your system is already at Solaris 1.1 (SunOS 4.1.3) or higher you can run JumpStart to upgrade to Solaris 2.X. After backing up your system you would execute the script, /etc/.install.d/re-preinstall-svr4 when in single user mode to perform the upgrade. The script uses /usr/etc/install/bpgetfile to try to locate a network version of the Solaris 2 CDROM. bpgetfile does an rpc broadcast to the local subnet to try to locate an install server with the install program. Failing that it checks locally for a mountable CDROM. Should it find either source it mounts the file system on /.stub/mnt. After checking to make sure that it has the necessary files for this architecture it starts the upgrade process and gives you a chance to back out. It reads any custom files that have been placed in /.stub to control the install.
