I read with interest this post about setting up a flash drive with multiple OS X installers. It confirms what I've suspected by my tests with just one OS (Lion).
However, a question occurred to me: How do you avoid multiple instances of "Mac OS X" appearing as possible boot choices? In other words, how do you know which one is which?
EDIT: I am referring to the situation when booting with the "Option" key held down, showing all available boot sources.
- Does the boot loader distinguish between them somehow?
- If not, can I (safely) rename the string in the "SystemVersion.plist" file on each partition?
