Subject: [PATCH] daemon.c: Open /dev/null read-write.
While daemonizing we redirect stdin, stdout and stderr to /dev/null,
which is considered good practice. We should, however, open these
two devices in read-write mode rather than read-only, since not being
able to write to stdout/stderr might confuse rsync and the hooks.
