Comment 1 for bug 573975

I had a 9.10 vmware VM and my clients was booting with PXE.
Then I upgraded to 10.04 and my clients stop booting for "permission" problems.
I do a ltsp-build-clients but that do not solve.
After some google search, I look at /etc/default/tftpd-hpa
Here i see that tftp folder now is /srv/tftp (before it was TFTP_DIRECTORY="/var/lib/tftpboot")
I look at /srv/tftp and see that all files are there with right permission.
Also, in /etc/default/tftpd-hpa now i have TFTP_OPTIONS="" while before was TFTP_OPTIONS="--secure"
I put TFTP_OPTIONS="--secure" than
sudo service tftpd-hda restart

Now my clients boot

Sorry for bad english, hope this help.
