Export nested mounts through NFS
I have the automounter set up on my server so that it will mount some DVD images on the loopback. (i.e. I go to /mnt/iso/FC7-i386/ and the Fedora 7 i386 DVD is mounted). What I would like to do it set up NFS so that I can export the top level directory (in this case /mnt/iso) and have all mounted subdirectories also be exported. I have the parent and automount stuff working, but I can't find any documentation that talks about some sort of recursive exporting. Has anyone done this, or do I have to explicitly add entries for each of the mounted image directories?
