FileHandle 0 in terms of Linux it is setting fsid=0 when exporting.
Which would explain why someone said Linux (NFSv4) automounts an exported
filesystem under another exported filesystem
ie mount servername:/ and be able to browes all exported/shared file systems
you have access to.
I don't think this made it into Solaris NFSv4 server.
Correct, we believe the client should do the work here, not the
server. The tough problem with letting the server pretend all
subshares are part of one big filesystem is that there can be
fileid/inode number collisions between objects in separate
underlying filesystems, and Posix applications can do bad
things in those cases. There's no graceful way to do this in
NFSv2/v3, but v4 solves it.
