      Alternatively, you can use a "du"-like script which avoids traversing
 the ".snapshot" directory:
#!/bin/perl
 #
 # Usage mydu [dir]
 #
 opendir (DIR, $ARGV[0]) || die "Can't open $ARGV[0] $!";
 @dirs = readdir(DIR);
 closedir (DIR);
 foreach $d (@dirs)
 {
    next if ($d eq "." || $d eq ".." || $d eq ".snapshot");
    system ("du -s $ARGV[0]/$d");
 }

stupidly, i
counted the space each data directory is taking with du -sk, so i got 
the snaps as well and all the numbers are off.  i guess today i'm 
going to be adding up directory sizes with a massive find -prune loop.

(or is there a better way?)
One trick for doing du's without encountering any .snapshot directories 
is to do the du within a snapshot.
