[I have also changed the /bin/csh defaults to /bin/sh
(which is my normal context).]
# more /boot/loader.conf
# Configure USB OTG; see usb_template(4).
hw.usb.template=3D3
umodem_load=3D"YES"
# Multiple console (serial+efi gop) enabled.
boot_multicons=3D"YES"
boot_serial=3D"YES"
# Disable the beastie menu and color
# beastie_disable=3D"YES"
# loader_color=3D"NO"
# shutdown -r now
And the beastie shows up and works just fine,
operated from the USB RPi keyboard.
My bias here is to have minimal differences from
the RELEASE and snapshot builds relative to the
reported problem. I still see no evidence of any
problem with use of the RPi keyboard to control
booting.
