So, I'd basically need to check the fstype for each of the directories 
of interest (they MAY all be on the same volume, but not necessarily).
    /var
    /var/run
    /var/log
    /var/empty
    /etc
So, how do I do that portably?  The 1.7 version of mount returns that 
information, but the 1.5 version does not.  What if I import your 
getvolinfo program
   http://cygwin.com/ml/cygwin/2007-08/msg00040.html
as one of the csih helper progs, and put it under /usr/lib/csih/ 
(alternatively, import getvolinfo into cygutils).

In that case, I wouldn't need to check for NTFS at all -- instead, I'd 
check for "FILE_PERSISTENT_ACLS[ ]*: TRUE", right?

Or is there a better way?
