Thanks for your reply Scott.

Yes, at least with Centos5 and fedora6 (2.6.18 kernels are what I am
testing with on both distros), i have configured the Root File System
Support via the "make menuconfig" option.
The following were the changes I made to the kernel:
1. Networking-> Networking options
* IP Level autoconfiguration
* IP DHCP
* IP Bootp
* IP Rarp
(enabled = *)
2. Device Drivers-> Network device Support-> Ethernet 10/100Mbit ->
nForce (my nVidia NIC)
3. File Systems -> Network File Systems
* NFS File System Support (changed from M to *)
* Root FS on NFS
.... I had to also disable on option: "Provide NFS Client Caching
Support" - the only reason is because, after I performed Steps 1-3 and
attempt to recompile the kernel, I had some make compile error that
pertained to FS cache; in searching/googling it was recommended to
disable this option. Upon disabling, the compile completed without
error.
... I have also just completed setting up a FEDORA 6 Root-NFS kernel
and root directory - and upon booting, I still get the same problems
as the prior mentioned CentOS5. Both are of the 2.6.18 kernel base,
and both give that same value: "sec=null" ... when the root NFS is
mounted.
Any thoughts?
Thanks in advance.
Vince
