Actually, as often as I need tftpd, I DO want it invoked manually. I am 
doing this on a notebook what has the firmware and config files for the 
switches.  Update the firmware, install the config files. Check that all 
is well and backup the config files.  Then take down tftpd for the next 
year or so.

So I don't want to run it from inetd.d.  The man pages says it CAN be done.

Do I still have to enable it?  Is this for selinux's use (perhaps the 
problem is selinux, but no logging saying so).
