Yes, my server is running tcpwrappers.  So I added:

	in.tftpd : 192.168.1.101

into /etc/hosts.allow, but nothing is changed.  Then I disabled
tcpwrapper on in.tftpd, and the situation stays the same.  The security
log shows the following:

	bootpd: Connect from 0.0.0.0
	in.tftpd: Connect from 192.168.1.101

So it looks like the connection is established successfully.  I guess it
is the configuration of the client's root filesystem that causes the
problem.  So when a system boots up, what's happening after the root
filesystem is mounted.  Does the init process takes over right away?
