In BSD/OS I set this from /etc/rc.  In NetBSD I havent because
   the shell doesnt support the "limit" or "unlimit" commands.

it does, however, support the ulimit command.
   
   I'm sure you could raise the limit for just inetd if you wanted
   to.  something like:
   
       /bin/csh -c "unlimit process; unlimit nofiles; inetd"

ouch ouch ouch ouch ouch.

/bin/csh -cf 'unlimit process; unlimit nofiles; exec inetd"

please.
