Don't read too much into the "hacked bsdinstall version", I ain't that
good. All I did was this.....
f_eval_catch $funcname gpart "$GPART_ADD_LABEL" \
zfs$index freebsd-zfs $disk || return $FAILURE
f_eval_catch $funcname gpart "$GPART_ADD_LABEL_WITH_SIZE" \
zfs$index freebsd-zfs 800Gb $disk || return $FAILURE
The raidz will boot if I pull the other drives and let it boot with just
the 4 zfs raidz drives so I know it will boot. Just have to get it to
play nice with the other systems (win7 and 10.0) and boot.
I just need to configure out how to make it boot with the other drives.
Hand holding required.
