xinetd is apparently executing with the privs of the root user, but if I
do a strings on in.tftpd there is a string in there
cannot drop privileges: %m
suggesting that tftpd doesn't run as root. In fact the man page says it
runs as nobody by default I see now.
Anyway it's moot because you show tftpboot wide open for anyone to write
into.
Nothing in /var/log/messages about the failed write? Add -v -v -v to
the options in /etc/xinetd.d/tftp and restart xinetd, then try again...
it should be chattier in the log and maybe you get a clue.
