To do this, you will need a storage medium (DVD, flash drive, or hard-drive partition) of at least 4GB in size, and then just follow these steps: After choosing Show Package Contents on the installer, navigate to this folder to locate the InstallESD.dmg image that contains the Lion installation (click for larger view).
Luckily the OS X installer contains all the materials you need to burn yourself a boot image of the installer, and all you need to do is access this image and then either burn it to DVD or restore it to another bootable storage medium. The Lion installer will download to your Applications folder and contains everything needed to create a boot DVD. Apple's approach to installing and managing your Lion installation does offer a decent amount of flexibility, but if you would like to have your Lion installation on DVD, then you absolutely can do this. While its availability solely as a download may have its conveniences, the lack of its initial distribution on optical or other media has been met with a decent amount of criticism, especially by those looking for options to troubleshoot and customize their OS installations. OS X Lion has been released and is available in the Mac App Store to download and install.
