 Yes, this is unfortunate, but normal, as I explained in an earlier post.
 
 The sshd process does not return any error (and thus the /etc/rc.d
 script doesn't either), because it has no way to know that its forked
 copy died.
 
 The solution to this PR is "don't run stuff on conflicting ports". :)
