create boot ISO from Mavericks Installer

Mount the installer image

hdiutil attach /Applications/Install\ OS\ X\ Mavericks.app/Contents/SharedSupport/InstallESD.dmg -noverify -nobrowse -mountpoint /Volumes/install_app

Convert the boot image to a sparse bundle

hdiutil convert /Volumes/install_app/BaseSystem.dmg -format UDSP -o /tmp/Mavericks

Increase the sparse bundle capacity to accommodate the packages

hdiutil resize -size 8g /tmp/Mavericks.sparseimage

Mount the sparse bundle for package addition

hdiutil attach /tmp/Mavericks.sparseimage -noverify -nobrowse -mountpoint /Volumes/install_build

Remove Package link and replace with actual files

rm /Volumes/installbuild/System/Installation/Packages
cp -rp /Volumes/install
app/Packages /Volumes/install_build/System/Installation/

Unmount the installer image

hdiutil detach /Volumes/install_app

Unmount the sparse bundle

hdiutil detach /Volumes/install_build

Resize the partition in the sparse bundle to remove any free space

hdiutil resize -size hdiutil resize -limits /tmp/Mavericks.sparseimage | tail -n 1 | awk '{ print $1 }'b /tmp/Mavericks.sparseimage

Convert the sparse bundle to ISO/CD master

hdiutil convert /tmp/Mavericks.sparseimage -format UDTO -o /tmp/Mavericks

rm /tmp/Mavericks.sparseimage

Rename the ISO and move it to the desktop

mv /tmp/Mavericks.cdr ~/Desktop/Mavericks.iso
