When you enter dev-mode,
Pressing Ctrl-U to boot from USB is DISABLED.
Booting any self-signed kernel from the SSD is ENABLED.
This replaces the "crossystem dev_boot_custom" argument with
"crossystem dev_boot_signed_only", which has the opposite polarity.
So if you want to dev-mode to only boot official kernels, you have to
explictly set it that way. If you leave dev-mode and then come back,
it will go back to the conditions shown above.
BUG=chrome-os-partner:5954
TEST=manual
Just run the factory flow. It was broken; this should fix it (except for any
workarounds that were added while it was broken; those may need to be
reverted).
