VMware custom OS X installer script adds support for VMware ESXi

I’ve updated the create_vmware_osx_install_dmg.sh script that I had previously posted about here. It now includes the ability to create an .iso file, which can be used with VMware ESXi servers running on Apple hardware. See below the jump for the details.

When running the script, the user will now be asked if they want an ISO disk image for use with VMware ESXi.

If the user selects Yes, both a .dmg and an .iso file will be created and stored in the output directory.

If the user selects No, a “— ISO disk image will not be created. Proceeding..” message will be displayed and a .dmg file will be created and stored in the output directory.

The virtual drives created by VMware ESXi for OS X VMs are not automatically formatted, so support for System Image Utility‘s AutoPartition.app has been included. AutoPartition.app runs before the installation of OS X to make sure the boot drive is formatted and named correctly for the automated installation.

The updated script is below and has also been posted to my GitHub repo. For more details on configuring and running the script, click here.


#!/bin/sh
#
# Preparation script for a customized OS X installer for use with VWware Fusion
#
# What the script does, in more detail:
#
# 1. Mounts the InstallESD.dmg using a shadow file, so the original DMG is left
# unchanged.
# 2. minstallconfig.xml and PartitionInfo.plist are also copied, which is looked for by the installer environment's
# rc.* files that first load with the system. This allows us to never actually modify the
# BaseSystem.dmg and only drop in these extra files.
# 3. Additional installer packages can be added using First Boot Package Install.pkg,
# which is added to the OS X install by way of the OSInstall.collection file. The instructions
# on how to use this package are documented here:
# https://derflounder.wordpress.com/2013/05/13/first-boot-package-install-pkg/
# 4. If desired, a second disk image in .iso format can be generated for use with VMware ESXi
# servers running on Apple hardware. The .iso file will also be stored in the output directory.
#
# Original script written by Tim Sutton:
# https://github.com/timsutton/osx-vm-templates/tree/master/prepare_iso
#
# Thanks: (brought over from Tim's original script)
# Idea and much of the implementation thanks to Pepijn Bruienne, who's also provided
# some process notes here: https://gist.github.com/4542016. The sample minstallconfig.xml,
# use of OSInstall.collection and readme documentation provided with Greg Neagle's
# createOSXInstallPkg tool also proved very helpful. (http://code.google.com/p/munki/wiki/InstallingOSX)
# User creation via package install method also credited to Greg, and made easy with Per
# Olofsson's CreateUserPkg (http://magervalp.github.io/CreateUserPkg)

    Great script. Just wondering if you know where I can find some documentation regarding the Autopartition.app? I was hoping to use your script to provide end users at remote locations a bootable USB flash drive containing your created image but have it perform some custom partitioning.

    I can see the plist, just trying to figure out whats the best way to implement it.

    We partition our HD’s with two partitions SYSTEM and DATA and my post image script binds the system to AD and redirects local /Users to DATA volume.

    I was hoping to use your script for both Macs that have just been purchased (HD is Macintosh HD, so AutoPartition would do its magic) and older systems requiring a re-image (already partitioned) so AutoPartition would not do anything, and installer would just erase and install the SYSTEM partition.
