This is a quick band-aide until a longer term solution happens. There was the suggestion of adding a hack so that if there was no lua, we could use the 4th interpreter instead. There's a number of ways to do this, but they all involve a bit of work. There was the suggestion of installing a userboot_{lua,4th}.so and hard linking (but this provides a built-in way to get the right userboot_*.so to use with a bhyveload -l lessening the burden). The notion of putting some smarts into bhyveload to cope, since it's also updated at the same time that userboot.so is, typically. There may be another notion as well. Working through the details and will present a plan when I have it. Warner
