Future Proof Installs

Attempting to future-proof an installation. Now that ZFS is upon us I'm beginning to think how to future-proof new installations so that when we get to boot from ZFS I can live upgrade to that and let my existing partitions be absorbed into the zpool. Yes I can just add the partitions to the pools but there should be a better way.
On my next installation I will be putting the two root file systems, one for the boot and one for live upgrade, and swap at the end of the disk rather than at the beginning. Then when they are no longer needed as ZFS can handle all my disk I can grow the ZFS partition and therefore the zpool into each of the old root partitions as and when they are not needed. For the laptops this is not that important as the amount of data is small and by luck rather than judgement I can move all the data using a combination of live upgrade and zfs mirrors. However for the new server I'm going to be building for home this will be crucial as for large amounts of data that would be painful.
