That’s possible, though I don’t know why. If you still have the fog installer file (fog_0.32.tar.gz) run these commands to get tftpboot back:
[code]cd /opt
wget http://sourceforge.net/projects/freeghost/files/latest/download?source=files
tar -xzf fog_0.32.tar.gz
cd fog_0.32
cp -r packages/tftp /tftpboot
chown -R fog:root /tftpboot
cd /opt
rm -rf fog_0.32[/code]
That should give you back the tftpboot folder and apply the proper permissions. However, did you rerun the installer after getting NFS to work? If you didn’t your install may not be complete.
