link/bind a directory into a NFS exported folder

  • 772

Have a Linux PC and an ARM-board. Want to boot the ARM-board into a rootfs hosted on the PC (cross/remote)

I export a rootfs in my home, so /etc/exports looks like:

/home/user/rootfs 172.20.20.0/24(anonuid=0,anongid=0,async,rw,no_subtree_check)

Now I want that a certain folder (lets assume /home/user/example/opt) is linked to /home/user/rootfs/opt. That works fine via a mount bind. So at PC I can navigate through directories and see that files in /home/user/rootfs/opt BUT: The device that boots into that NFS doesn't see this /opt folder (or the content in it).

Do I have a chance to solve that? Maybe I need a different approach or have to add a line in /etc/exports fo my PC?
