Hmmm... Just to be sure - does the primary bootstrap (the bootxx_*) go to
the start of the outer gpt (the dk0 raid partition), or to the start of the
inner gpt (the dk1 root partition)?
From browsing <sys/arch/i386/stand/mbr/gpt.S>, it looks as if the sector 0
boot code knows how to walk the gpt table. But does it descend recursively,
i.e. look at gpt partitions within a (special, e.g. raid) gpt partition?
And does a primary bootstrap look at other partitions but the one it was
