Solaris2 (as MBR partition type) - our tools assume there is one Solaris2 partition. As you have 6TB disks, you can not really use MBR (it does not allow to address that big disks).

with zfs pools, the automatic partitioning code is using tag usr (with GPT it is translated to UUID). We do not really care about slice tags, but some other systems do (so they may be meaningful with multi-boot setups).
