Just noticed that there is a '-h <host>' switch to 'sudo', so the
following works to allow rsync on the localhost without 'ssh'
$Conf{RsyncClientPath} = '/usr/bin/rsync';
$Conf{RsyncSshArgs} = ['-e', '/usr/bin/sudo -h'];
$conf{SshPath} = '';
The resulting command is of form:
usr/bin/sudo -h <host> /usr/bin/rsync --server --sender
-slHogDtpAXrcxe.iLsf --iconv=UTF-8
Since 'host' is the localhost (by choice), adding the '-h <host>' switch to
sudo doesn't do anything different...
Still a bit klugey but at least it's simple...
