suseinst

The suseinst.sh sample script is used to perform an unattended installation of a supported SUSE Linux Enterprise Server operating system.

The variables and paths must be specied before the operating system can be installed.

CAUTION: It is recommended that you consult your SUSE Linux Enterprise Server operating system documentation and

unattended deployment documentation to develop a thorough understanding of the unattended installation process before

attempting to perform a full scripted deployment.

NOTE: While installing Linux, ensure that you install grub in the boot partition. Otherwise, you cannot boot to the utility partition

by pressing the <F10> key during reboot.
