The best tools (IMO) for this are dump and restore. If you have external storage, storage on another system accessible by a reasonably fast network from your laptop, or dvd burner (if the example here works, I haven't tried it) then this will definitely be your best option. Make your backup using dump and verify that it's complete, intact, and able to be restored from a fixit CD. Then (still from the fixit CD) blow away your existing partitions, make your new ones, and run restore to put your data back. If that option doesn't appeal to you you should still make and verify a complete backup before doing anything else. Depending on how much free space (and possibly swap) you have on your disk, you could possibly do a few different passes using growfs (in the base system) to this effect: identify next (in block order on the disk) partition to be grown. if there is no (or not enough) unpartitioned space after the growing partition, move everything from the next partition to other partitions, possibly creating temporary partitions closer to the end of the disk, or permanently relocating one or more partitions to the end of the disk, or temporarily converting your swap partition to a filesystem (be sure to not use it as swap for the duration, of course)... destroy the newly freed partition use growfs if there's room and a need, recreate the destroyed partition and restore its contents from elsewhere repeat I share your doubts about Linux utilities being able to handle UFS (esp. UFS2) filesystems correctly.
