not the iso .. du -s of the ext2 knx_root partition.
I was actually used a reiserfs at first. then, I gave it a try on a ext2
partition without
finding any substential difference ( on ext2 it was a tiny bit smaller. but
I had also small difference
when using cp/afio/rsync even on the same partition !!).

here we go after a rsync
du -sk *
4476 bin
1404 boot
4 cdrom
96 dev
20144 etc
4 floppy
4 home
4 initrd
32752 lib
16 mnt
200172 opt
4 proc
4 root
7348 sbin
0 tmp
1680128 usr
105064 var
0 vmlinuz
vs
du -sk /KNOPPIX/*
4283 /KNOPPIX/bin
1389 /KNOPPIX/boot
2 /KNOPPIX/cdrom
688 /KNOPPIX/dev
12528 /KNOPPIX/etc
2 /KNOPPIX/floppy
2 /KNOPPIX/home
2 /KNOPPIX/initrd
30225 /KNOPPIX/lib
8 /KNOPPIX/mnt
190183 /KNOPPIX/opt
2 /KNOPPIX/proc
2 /KNOPPIX/root
6996 /KNOPPIX/sbin
0 /KNOPPIX/tmp
1441891 /KNOPPIX/usr
80494 /KNOPPIX/var
0 /KNOPPIX/vmlinuz
so we see that there are differences in almost all directories .. the big
differnce beeing
on usr...
I looked into boot .. they are exactly the same but "du" differs...

We can notice that the size of System.map-2.4.19-xfs is a multiple of 1K
:500*1024=512000 ...
the real size according to ls did not change though!
could this be the trick ?
( on the reiserfs partition I have even bigger du -sb usage [ ls giving the
same result !!!! ]

Is this also happening with you guys?
or is this only me ;-)
probably very irrelevent but here we go anyway : the pc on which i am trying
to build my iso
is an old PII 400Mhz with 200M Ram + lots of swap, running RH7.3 when not
building the iso ]
do you need some other troubleshooting ???
you think that this is the problem?? I really don't get it :( :( :(
thanks again for your precious help.
fabrice.
