If one were booting from ZFS, would you be out of luck (since you wouldn't be able to access the zpool.cache before booting), or is there a way around this problem?

Is there any way today, to avoid using the boot assigned drive name (e.g. /dev/ad2) when creating the zpool? Again just wondering, I don't need a solution this year... Thanks, Gary
