I thought the 'dd' commands were being run by the installer, not gpart?

The configuration gets logged to pc-sysinstall.log. It contains a
rootPassword line.

ahci is there but not ATA_CAM: otherwise the devices would be ada0
instead of ad0.

The start sector is being specified as 63, which will result in
unaligned accesses.

Turns out VMWare defaults to 256MB RAM which isn't enough to start the
installer - Xorg was being killed when the system ran out of memory.
Bumping the memory to 2500MB fixed the problem.
