The example above is a direct map entry with no root offset. The
semantics are different than if it were an indirect map with browsing
enable.
I tested this out against other automount implementations and discovered
that direct map entries with no root offsets should be broken down into
several direct map entries with root offsets.. so:
/usr /man1 server:/usr/man1 \
/man2 server:/usr/man2
is the same as the two distinct entries:
/usr/man1 server:/usr/man1
/usr/man2 server:/usr/man2
Now that I think about it, the discussion in my proposal paper about
multimounts with no root offsets probably isn't required.
