Thank you for pointing me to that. In fact it's started as
/etc/rcS.d/S40netenv, because it is needed before
/etc/rcS.d/S40networking. 

This means:

- netenv (as it currently is, using /usr/bin/stat) cannot be used on a
  system that has /usr on an nfs filesystem 

- anybody who reasonably wants to use netenv, a program for laptops or
  other portables, will have /usr mounted locally

- still I have to think about a way to prevent harm when somebody
  accidently installs it on a machine using nfs for /usr.

As I don't use nfs at all, I don't know how to figure this out safely
during configure. Can you point me to the right place?

Thanks, Frank
