Hi,

I don't see this behaviour:

# touch new-file
# ls -al new-file 
-rw-r--r--  1 root root 0 Oct  6 16:59 new-file
# du -sk new-file 
0       new-file
# uname -a
Linux aurum 2.6.9-42.0.2.ELsmp #1 SMP Tue Aug 22 17:26:55 CDT 2006 i686 i686 i386 GNU/Linux
# echo > new-file
# ls -al new-file 
-rw-r--r--  1 root root 1 Oct  6 17:01 new-file
# du -sk new-file 
4       new-file

We use ext3 with options 'defaults' on a local SCSI disk.
