Based on man automount, you are wanting a kind of replicated filesystem, but I
don't see a way to specify more than one set of options for a given mountpoint.
In that part of the options is the filesystem type, the most direct answer
would be to try the following in your /etc/auto_master
# key/location mount options filesystem
/shared-vm -t nfs3 vm:/export/shared
/shared-fuse -t fuse :/export/fuse
If you can share the filesystem under the same protocol from both methods, then
you can put it on one line (like a replicated filesystem according to the man
page:
# key/location mount options filesystem
/shared-vm -t nfs3 vm:/export/shared :/export/fuse
Hope that helps,
Nathan
