Specifications

%firstboot
Creates an init script that runs only during the first boot. The script has no effect on subsequent boots. If
multiple %firstboot sections are specified, they run in the order that they appear in the kickstart file.
NOTE You cannot check the semantics of %firstboot scripts until the system is booting for the first time. A
%firstboot script might contain potentially catastrophic errors that are not exposed until after the
installation is complete.
--interpreter
=[python|busybox]
Specifies an interpreter to use. The default is busybox.
NOTE You cannot check the semantics of the %firstboot script until the system boots for the first time. If the
script contains errors, they are not exposed until after the installation is complete.
Differences Between ESXi 4.x and ESXi 5.0 Scripted Installation and Upgrade Commands
Before you perform a scripted ESXi installation or upgrade, if you are familiar with ESXi version 4.x scripted
installation, note the differences between ESXi 4.x and ESXi 5.0 scripted installation and upgrade
commands.
In ESXi 5.0, because the installation image is loaded directly into the host RAM when the host boots, you do
not need to include the location of the installation media in the installation script.
ESXi 5.0 supports scripted upgrades in addition to scripted installation.
