Hey everyone,
I wanted to share a method I've borrowed (and tweaked) from other sites in regards to making a bootable Yosemite installation DVD that works.
Before going any further, I fully know and agree that DVD installation media is old and being phased out and replaced by bootable USB installer media. That's fine. This guide however is for those computer/network technicians who still need AND use optical media for our own systems or customer systems. PLUS it's more economical to have a small CD booklet with each OS X version readily available for quick use.
So if you want to make issue over why I created a DVD guide vs USB, just don't waste your time.
So far this is confirmed with Developer Preview 1. Will edit as I confirm with other previews/betas.
Simply open up terminal (Hard Drive - Applications - Utilities - Terminal) and copy and paste each command. Then burn the *.iso file created on the desktop. I had issues burning on the MacBook Pro 13, so I copied it to my Windows PC and used imgburn which works just fine.
I've included comments detailing what each command does... in case anyone is interested.
Mount the InstallESD image to 'install_app' without verifying or opening Finder
Convert the BaseSystem image to grow with content (UDSP)
Resize the SparseImage to 8GB / DVD DL size
Mount the SparseImage to 'install_build' w/o verification or using Finder
Remove Packages Shortcut from temp mounted image
Copy full Packages folder to location of Packages Shortcut
Copy BaseSystem.chunklist and .dmg from /install_app to /install_build
Unmount temp mounted images
Determine size of SparseImage file and Shrink to min file size allowed
Convert the SparseImage File to DVD/CD master (*.cdr type) for export (UDTO)
Delete the SparseImage file
Move CDR to desktop and rename to ISO
Now you will have "Yosemite.iso" on your desktop. You can try using Disk Utility, Toast, or even a Windows PC to burn this image. My experience created too many coasters burning this with Disk Utility or Disco. But was flawless on IMGBURN on Windows. Go figure.
I would like to thank and give credit to the two following sites. I took my method from the terminal commands posted by "tywebb13" for creating bootable Mavericks discs, and similar terminal commands by Dan Frakes over on MacWorld aimed at specific Yosemite changes.

Mount the InstallESD image to 'install_app' without verifying or opening Finder
Code:
hdiutil attach /Applications/Install\ OS\ X\ 10.10\ Developer\ Preview.app/Contents/SharedSupport/InstallESD.dmg -noverify -nobrowse -mountpoint /Volumes/install_app
Convert the BaseSystem image to grow with content (UDSP)
Code:
hdiutil convert /Volumes/install_app/BaseSystem.dmg -format UDSP -o /tmp/Yosemite
Resize the SparseImage to 8GB / DVD DL size
Code:
hdiutil resize -size 8g /tmp/Yosemite.sparseimage
Mount the SparseImage to 'install_build' w/o verification or using Finder
Code:
hdiutil attach /tmp/Yosemite.sparseimage -noverify -nobrowse -mountpoint /Volumes/install_build
Remove Packages Shortcut from temp mounted image
Code:
rm /Volumes/install_build/System/Installation/Packages
Copy full Packages folder to location of Packages Shortcut
Code:
cp -rp /Volumes/install_app/Packages /Volumes/install_build/System/Installation/
Copy BaseSystem.chunklist and .dmg from /install_app to /install_build
Code:
cp -rp /Volumes/install_app/BaseSystem.chunklist /Volumes/install_build
cp -rp /Volumes/install_app/BaseSystem.dmg /Volumes/install_build
Unmount temp mounted images
Code:
hdiutil detach /Volumes/install_app
hdiutil detach /Volumes/install_build
Determine size of SparseImage file and Shrink to min file size allowed
Code:
hdiutil resize -size `hdiutil resize -limits /tmp/Yosemite.sparseimage | tail -n 1 | awk '{ print $1 }'`b /tmp/Yosemite.sparseimage
Convert the SparseImage File to DVD/CD master (*.cdr type) for export (UDTO)
Code:
hdiutil convert /tmp/Yosemite.sparseimage -format UDTO -o /tmp/Yosemite
Delete the SparseImage file
Code:
rm /tmp/Yosemite.sparseimage
Move CDR to desktop and rename to ISO
Code:
mv /tmp/Yosemite.cdr ~/Desktop/Yosemite.iso
Now you will have "Yosemite.iso" on your desktop. You can try using Disk Utility, Toast, or even a Windows PC to burn this image. My experience created too many coasters burning this with Disk Utility or Disco. But was flawless on IMGBURN on Windows. Go figure.
