1. service nfs start
2. pkill rpc.mountd && umount /proc/fs/nfsd
3. exportfs -iv *:/tmp

Actual results:

Unmounting /proc/fs/nfsd will break a number of things. Its invalid configuration something that is not supported.

-In RHEL7.0 it's OK;

-Sometimes we need build testEnv by err config to cover many code branch.
Though the env has an "error" config.
But This is a code logic error:
Anyway the code should recognize this special options "-test-client-",
 and should not give that err message to confuse our customers or users.

This is not a supported configuration. Customers are
not going to be killing things and unmount things
with the expectation of a stable/errorless system.

This is pure luck! ;-)

Ok,,steved. but I still think there is a logic defect..

Why in RHEL-5 and RHEL-7 test pass?
