Hi again geom folks,
I tried executing the following commands in a script to create a
clean MBR partition and it's not clear to me where I'm messing up with
the process in the first step:
% gpart add -b 34 -s 128 -t freebsd ad4 # exits with a non-zero code
gpart: 22 geom 'ad4'
% gpart create -s MBR ad4
gpart: 22 scheme 'MBR'
% gpart bootcode -p /boot/boot0 -i 1 ad4
gpart: No such geom: ad4.
% uname -a

All I see when I set debugflags to 255is a bunch of output in the form:
