I've tried to split up root in 20MB image and usr in 160 MB Via loader.conf root becomes md0 and usr md1 and panic occurs even when they are split I had to get rid of md1, to be able to boot with md0 as a root. What exactly imposes limitation, inside kernel's code to SIZE of an image? My hardware definatelly isn't ... Is this different on amd64? I've tested this, only with i386. Domagoj S.
