Details:

using this example code:

  NSFileManager *fm = [NSFileManager defaultManager];
  NSDictionary *attributes = [fm fileSystemAttributesAtPath: @"/home"];
  NSNumber *freefs = [attributes objectForKey: NSFileSystemFreeSize];

The documentaiton says this should return the free space "in an appropriate
measure unit". Usually it is byte, but it could be blocks for example.

On NetBSD I get:

2007-12-31 00:00:13.346 NSFMTest[225] size is 2263040000

while free blocks are:
Filesystem  512-blocks      Used     Avail Capacity  Mounted on
/dev/wd0a     37947292  10331604  25718324    28%    /

conveniently expressed in 1k blocks:
Filesystem  1K-blocks      Used     Avail Capacity  Mounted on
/dev/wd0a    18973646   5165802  12859162    28%    /


On FreeBSD the thing is even worse: freefs is nil. Nothing gets returned, as
if the quantity coulnd-t be read or (according to comments inside
NSFontManager.m) the path didn't exist.
