Hook another iSCSI target before autoboot/scriptlet help?

You'll need to use a custom ipxe script to do what you're after instead of doing everything directly in the DHCP server. If you want to snapshot I would recommend you boot the software you need to perform the snapshotting with an argument specifying the disk to use. A sanhook before you run said software should ensure it ends up in iBFT so your OS can fetch that info from memory after boot.
