New oddity that I’ve stumbled over with 8.0_RC1. Got it all installed with GPT partitions (wedge 1 is EFI, wedge 2 is root, wedge 3 is swap, etc). Boots up and runs fine, so I moved to the next step and install xen. But when I try to boot up it insists that root is on the first wedge /dev/dk0, not /dev/dk1 where it found the kernel.
I don’t see an option in boot.cfg to force it to use the correct wedge. Is it that the xen kernel doesn’t understand wedges? Have I missed it or is this a bug? BTW, booting up with GPT partitions without xen properly selects /dev/dk1 as the root and /dev/dk2 as swap.
