Log:
  lualoader: disable autoboot on high-level interpreter errors
  
  If we hit an error at this level, we are almost certainly not in any kind
  of sane state where autoboot can do the right thing. Instead of letting it
  try and probably failing, disable autoboot so they immediately get kicked
  into a loader prompt for manual remediation/diagnosis.
