This use of select is questionable. In general it is bad to select
a symbol with dependencies.
In this case the dependencies of NFSD_V3 are duplicated for NFSD_V4
so we will not se erratic configurations but do you remember to
update NFSD_V4 when you add a depends on NFSD_V3?

But I see no other clean way to do it rithg now.
