we're running 0.40 on Tru64 5.1A -- I looked in the changelog to see
if 0.41 would solve the problem, but it appears there is no 0.41
changelog ;-) -- I will try it, though

truss output is attached, stopped after client timeout -- tftp was
launched manually with the following opts :
# in.tftpd -u root -l -r blksize /var/tftpboot

a short tcpdump output is also attached, which suggests tftpd does not
bind to the alias (as the client gets ICMP unreachables).
