I disagree. These are read only mounts. How is it an idiotic design to
provide a little extra availability by switching to another server in the
list if the mounted server becomes unavailable?
Furthermore, the fact that it is equally applicable for static mounts
does not make it an obvious NFS issue. I submit it's both an NFS and an
autofs issue...
