Hmm, if I remeber correctly there dash that is used as /bin/sh on Debian
(and supposedly on Ubuntu) that does not understand the &> syntax so the
messages may be reversed because the commands are executed on background
(instead of the output redirected to /dev/null).

Try to remove all '&> /dev/null' from the script and try again.
