I wrote up a script to do the heavy lifting for installing a completely zfs system on a sparc64 machine. http://www.pix.net/ftp/pub/freebsd/sparc_zfs_setup.txt The 12GB space for zfs is appropriate for a 18Gb disk, and allows the remainder of the disk space to accommodate a 4Gb-ish swap space, for crash dumps. The swap is placed at the end of the disk, since that's the slowest part to access. -Kurt
