Great doc, thanks! I was able to get the first part of the 2nd approach
booting from the gm0 mirror, but after booting and trying to add my da0
to the mirror, it does not recognize the device...I tried re-splicing
the drive in sysinstall with no help...

files# gmirror configure -a gm0s1
No such device: gm0s1.
files# df -h

files# ls -lah /dev/mirror/

Again, not sure where mine is getting the s1c devices...while the data
mirror was setup with another doc, the gm0 setup flawlessly following
your 2nd approach.
