Not only have I considered it, I've done it! I've been meaning to
post a follow up message to explain exactly how in case other people
are stuck in the same place but hadn't got around to it yet. Below is
the shell script I'm using to create a bootable FreeBSD system. I've
tested it successfully under QEMU and plan to try it on real hardware
soon. This was indeed much easier to write that than to figure out
why sysinstall doesn't work. Thanks for the link. I'll read it and
see if there's anything in there I can use to improve my script.
