AFAIK, binary, no-conversion, and raw-text-unix are completely equivalent. There might have been an earlier version of Emacs where `binary' was not handled as binary, but that was clearly a bug because `binary' says very clearly what it means. So I recommend to use `binary' when reading a binary file because it's obviously the right thing and if things go wrong it's clear that it's a problem with Emacs rather than with the elisp code. The bytes read from /dev/urandom have nothing to do with text, so `raw-text-unix' is just a bad choice. Stefan
