Yes.  This has existed at least from OpenSSH 2.0 (as long as I have been
using it).

Starting sshd fails because incoming ssh connections are registered as the
same sshd daemon processes as the one being started.  This happens in
daemon() in /etc/rc.d/init.d/functions.  The culprit is:

---
       [ -n "$pid" ] && return
---
where $pid is the number of incoming sshd connections plus one if running
sshd server at the moment.

The following is not probably not the clean solution, but I don't think
daemon keyword _can_ be used with sshd. :-/
