You can find the resulting HOWTO document under > http://people.freebsd.org/~rse/mirror/ Congratulations on a useful and comprehensive HOWTO! I have only one question: in the first approach ("Whole Disk, Acceptable, Less Flexible"), why do you create a slice if you are using the whole disk anyway? Is this simply because it's good form to put a valid partition table on a bootable PC disk? The reason I ask is because when I set up my bootable gmirror (using a technique similar to the one you describe) I omitted the fdisk step and used bsdlabel on (my equivalent of) /dev/mirror/gm0 (not gm0s1). I've not had any problems booting the mirror, nor in using it. It also means one less GEOM layer to go through, right?
