Unfortunately doing an upgrade from 5 to 6 with sysupgrade still
requires some manual handholding.  I haven't had a chance to make this
better yet :-/

The key trick is that you must ensure there is a reboot between the
kernel upgrade and the userland upgrade. Something like:

# for step in fetch modules kernel; do sysupgrade $step || break; done
# reboot
# for step in sets etcupdate postinstall; do sysupgrade $step || break; done
# sysupgrade postinstall fix [any checks that fail, which will probably happen]
# sysupgrade clean
