How to export Knoppix /home for NFS?

I'm trying to export the /home directory in Knoppix 3.6 cdrom
as an NFS share for other computers to use.

The problem is /home is symlinked to /ramdisk/home.

I get errors when I
exportfs -rav
whether I specify
/home or /ramdisk/home or /ramdisk/home
in the /etc/exports file.

No problem exporting Knoppix / for read write access to the rest of the tree but that excludes since it's on a different volume (the ramdisk).

But I can't seem to mount
/home -> /ramdisk/home
no matter what I put in /etc/exports.

What should I put in /etc/exports to allow me access to home?

Surely someone has done this.
