Snow Leopard; can I boot from disk image (DMG)?

[glossywhite]

Hi. I just got Snow Leopard installed. Can I boot from DMGs? ... I hear you can, but can't find confirmation.

Thanks

No

How sure are you, and can you substantiate this?.

How would it even be possible?

You need to restore the dmg to a hd partition, usb key etc if you want to boot from it.

I would like to know as well.

I'm guessing you pirated Snow Leopard and don't have a dual layered DVD to burn the DMG to.

Ha.

Alright genius, how would he use a Snow Leopard only feature to install his pirated copy of Snow Leopard if he doesn't already have Snow Leopard?

Way to go genius, you caught him.

Yes, granted - been doing that for three years, but my specific question is can I boot from an IMAGE.

You've evidently never used NetBoot.

From what I have read, you need to have partitions with a disk image stored on it. From the Appleinsider link I gave, it states you can only have one per partition this may have changed. I will give it a shot with an external drive with disk images on it.

I'd also like to know if this is possible... this was a new feature I was looking forward to.

Me too. I guess they forgot to implement this feature...

Being able to boot from a dmg is not a snow-leopard thing. Rather is is very similar to setting a manual netboot. You have to get a kenel in place, and then set the boot image to a file:// url. There are lots of little tricks to it, and so far I have only done it by scripts.

Now there are huge caveats to it: the image is not mounted read/write, so it is really only useful for booting installer images.

Eventually I will get around to figuring it all out and documenting it, but for the moment it is really not useful for most people.
