On my machines, the 530s, there are a number of filesystems exported
to be mounted by a number of other machines here.

By exprience, I learned that mounting NFS filesystems by the
hard/foreground options may cause the machines hanging, while
by the soft/backgroud options seems to work OK.

Here comes a problem: If some machine DOES mount my exported filesystems
by the hard/foreground optins, it may cause my machines hanging. Is there
any way to configure my exporting filesystems as follows:
   Only the machines which use the soft/backgronud options will be allowed
to use my exported filesystems.

Is it possible? Or is there any other way to solve the problem?

Thanks in advanc for any advice!
