It seems the above procedure is not quite right, at least on JunOS 7.3R1
I needed the following:

sysctl -w machdep.bootdevs=pcmcia-flash,compact-flash,disk,lan

Instead of:

sysctl -w machdep.bootdevs: pcmcia-flash,compact-flash,disk,lan

Is there any known reason why an M7i might do this? We had an otherwise
happy M7i do this on a reboot today, it had been cleanly shutdown, and
then re-powered.
