You can mount the NFS root read-only and modify startup
scripts/fstab/etc.
so that /var and /tmp are mounted as ramfs or tmpfs. Use some soft links
to provide mutable files in previous mount points. Works great.
And nobody is going to wreck the NFS root by mistake.  :-)
Throw in additional services: PAM, NIS, etc.
ELDK is not an end-product, it's a starter-product ;-)
Thank goes to DENX Software Engineering for their nice package.
BTW, ELDK 4.1 has been released recently, and it includes among
other things Xenomai and the long awaited uClibc support.

Have fun.
