Ok, so as of NW 6.5 SP3 and SP4 we get the new Extended Mac namespace
support in NSS, whatever exactly that means.

1) My first question is, how do you tell if a volume is set with this
switch or not?

2) Same issue for the case-sensitive or case-insensitive flag? (Short
of trying and seeing the results).

3) How do you know you need to use nsscpt.nlm to copy the namespace from
Unix to Extended Mac?
