</div>I am also using a Gentoo PXE client. I found, that you cannot set NFS<br>
mount options as kernel parameters in pxelinux.cfg and 1024 is a hard<br>
coded block size in the scripts from genkernel. How did you get around<br>
this? I modified the initrd.scripts.<br>
<br>

<br>
This is more important since kernel 2.6.27, because from there on, NFS<br>
remount options in /etc/fstab are not allowed to differ that much from<br>
the initial options apparently.<br>

I will try to remember to post exactly what I have when I get home. One thing I did notice if I had an incorrect parameter, pxelinux.cfg would ignore all of the options and the nfs options were different in pxelinux vs what I have in fstab. Maybe this is your issue.<br>
