Okay, I wasn't sure whether I invoked the '-v' option correctly, but I
guessed at putting it in both of the files '/etc/xinetd.d/tftp'
and /etc/xinetd.d/tftp.k12ltsp.rpmsave' by adding a 'v' to the line
thus:
"server_args		= -sv /tftpboot"
			    ^

Whether or not that worked, I can't say, but a check
of /var/log/messages gave this output (cut to delete irrelevant stuff):

Now, that's all Russian to me.  I hope it sheds light on the matter to
