EACCES in mount.nfs

EACCES in mount.nfs

[Chuck Lever]

Hi Steve-

There is an important case in mount.nfs where EACCES is temporary:   
The kernel's rpcbind client returns EACCES if the remote rpcbind  
server replies that the requested service is not registered.

It would be easy enough for the kernel's mount client to remap that  
error code into something unique for the mount system call.

Sorry for the delayed response... I spent most of last week
off line due to Red Hat moving to a new building...  fun, fun, fun! :-\

I guess I see the reasoning behind this... a server could be coming
up so the mount should hang around waiting for that...

I would think ENOENT would be a better mapping for RPC_PROG_UNAVAIL.

But that still leaves the possible problem of the mount not waiting 
around for servers to come up... Or do we even have to worry about 
mounts failing because a server is not up yet?  I'm beginning to
think not...
