self image

[AlessandroPPC]

Dear Wolfgang Denk,

I'm just looking at the SELF image and I observed that when I extract the
image and try to rebuild it
(without adding or removing any files) the dimension of result file is about
9KByte greater  than the original.
I have followed the procedure "How to increase the Size of ramdisk" to
generate an 8MByte ramdisk thus I
was expecting a small increase of the bytes amount, but never as reported.
Do you think I'm wrong somewhere?

Here enclosed is the script file.

any helps would be apreciated.
Many thanks
Alessandro.
