Well, there's one regression that prevents me from testing a regression. In 
gmirror(8) and still on 8.x it is described how to do kernel dumps on a 
gmirror, using /etc/rc.early. Yet, /etc/rc.d/early.sh has been removed and a 
grep for early in the /etc tree, has not shown me that there's a replacement 
in place.

I'm trying to see coming sunday (downtime) if a bug has re-occured in 8.x 
(kern/122572) and would like to de-activate one component of the mirror, 
install, reboot and if garbage is written to the disk again, use livefs tools 
+ rc.early to boot from the de-activated mirror.

So my questions are:
- What should really be in NOTES for gmirror(8) in 8.x?
- Is it possible to deactivate a mirror component, hose the active component 
and nextboot from the deactivated one, preferably without opening the case?
