Just from the loader it looks good:
...
Failed to find bootable partition
Startup error in /boot/lua/loader.lua: seconds
LUA ERROR: cannot open /boot/lua/loader.lua: no such file or directory.
can't load 'kernel'
Type '?' for a list of commands, 'help' for more detailed help.

And yes - it actually boots from that point.
The question is how to get currdev properly into the loader.
It is using the DOS partition, so maybe I can add a loader script
onto that partition instead.
I have to deal with something being on the card anyways.
