If it's that easy that'd be awesome, all I need is an alternate grub entry.
Regarding the disk numbering, GRUB and other x86 loaders assume that the current "BIOS boot disk" (one passed from BIOS as the boot device) is always number zero. Numbering of secondary drives may vary from boot to boot (i.e. if you boot from one or another disk of a mirrored root).
Or maybe not. I guess this was findroot() in sol10 but in sol11 this seems to have gone away.
I haven't used sol11 yet, so I can't say for certain. But it is possible that the default boot (without findroot) would use the bootfs property of your root pool. At least that's the way it worked in intermediate SXCE releases, where you had to set the whole bootfs path (zfs dataset name) in grub menu, or use the bootfs property.
Also, I was wrong about the disk target. When I do the install I configure the USB stick at disk0, seen by Solaris as c3t0, and no findroot() line gets written to menu.lst. Maybe it needs that line when it boots as a USB still on real hardware? I'll try import/export and a reconfigure boot when I get a chance.
