Sharing a network mount, preferably with NFS
Hello,
I would like to share a 9p (Plan 9) passthrough/share to a VM via NFS (using a guest as an NFS server to share a directory from the host)

At the moment I am getting the error message: 'exportfs: /share does not support NFS export' when running exportfs -r on the guest, and the client is being refused a connection. I would assume this is because you cant 're-share' a share, similar to if I wanted to share a directory mounted from another NFS share. (although I have heard unreliable sources say this is possible).

Is there a way round this?

I have checked the NFS server works for other directories. I have also tried putting the 9p share inside another directory and sharing the outer directory (in case the system could be fooled by a fool), this removes the error and allows a connection, but the inner directory is empty, as if the 9p share is not mounted. (which it still is, at least on the guest)

Any help would be appreciated!

Thanks.

exportfs

exportfs(1B)					     SunOS/BSD Compatibility Package Commands					      exportfs(1B)

NAME

       exportfs - translates exportfs options to share/unshare commands

SYNOPSIS

       /usr/sbin/exportfs [-aiuv] [-o options] [pathname]

DESCRIPTION

       exportfs  translates  SunOS  4.x  exportfs options to the corresponding share/unshare options and invokes share/unshare with the translated
       options.

       With no options or arguments, exportfs invokes share to print out the list of all currently shared NFS filesystems.

       exportfs is the BSD/Compatibility Package command of share(1M) and unshare(1M). Use  share(1M)/ unshare(1M) whenever possible.

OPTIONS

       -a	       Invokes shareall(1M), or if -u is specified, invokes unshareall(1M).

       -i	       Ignore options in /etc/dfs/dfstab.

       -u	       Invokes unshare(1M) on pathname.

       -v	       Verbose.

       -o options      Specify a comma-separated list of optional characteristics for the filesystems being exported. exportfs translates  options
		       to share-equivalent options. (see share(1M) for information about individual options).
