You're right. I hadn't read the latest couple of messages (where the
revelation about the binary passwd database was mentioned). Oops!

Right... this is why I was confused about his ability to boot! ;)

Agreed. The only way to get around this would be to have a magic number
at the beginning of the file that you could use to detect the endianness
of the file, and then (potentially) swap bytes accordingly. Or, just
always use network byte order or whatever.
