Regarding the gmirror talk: I found this helpful, as well:

http://www.onlamp.com/pub/a/bsd/2005/11/10/FreeBSD_Basics.html

Has there been any talk of a "gmirror aware" sysinstall that would
adjust the size of the disk layout by one sector to ensure that the
metadata is not overwritten?  (and perhaps make loader.conf and fstab
changes)

As I understand it now, the user has to manually account for this at OS
install, and adjust the disk layout accordingly... yes?
