FIRST: I do not know if the corruption where really caused by rsync!

I had made a copy of the corrupt tree and use it know to find out
what kind of corruption ocurred.

I knew that there where problems installing packets with a i686
installation of SuSE 9.2. So I searched the suspicous content of the
first SuSE 9.2 DVD for *.i?86.rpm files for what rpm -K reported a

I got a list of 101 broken files.

I compared them with their corresponding non broken versions by using
"diff -u" on textfiles created with "od -x".

A typical result (samba-3.0.7-5.i586.rpm) :
--- /tmp/ok.txt 2005-09-12 16:26:03.749124638 +0200
+++ /tmp/broken.txt     2005-09-12 16:26:04.112057459 +0200

There where just very few single bits (117 in 101 files) that where changed in
the broken files.

I would be quite happy to I find solution for this mystery.

I hope it's not rsync!
