According to the identd man page, the daemon can be run either via inetd or from init (or inetd) if it is built with threading support. If it has threading support and started from inetd you can use the -l swith and the wait option. The entry in inetd.conf in 6.1 has the -l switch but also nowait instead of wait. I guess either the -l swith should be removed or nowait changed to wait (assumeing it has been built with thread support).
this is fixed as of the beta, as identd runs standalone, and the inetd.conf entry is commented out.
