Hrmm, I need to look through that commit again, but on a first glance I 
cannot see code doing the sorting for ext3/ext4 only (e.g. by checking 
the fsid). So while I like the general approach, it will have the 
opposite effect for some file systems. I will report that back on the 
coreutils list.

Thanks a lot for the pointer to the commit!


Cheers,
Bernd
