I've seen this one before; bootup is a "special" configuration group that is
protected.  It boots from that when you have made config changes and then
done a WARM boot.  The way out of this is to do a COLD boot.

When updating your config, always boot the next time with a START NORECOVERY
and you'll be ok.
