I've seen problems with our SuSE Linux installation- and updateserver. After
moving to a bigger disk I had trouble with SuSE complaining about corrupted
rpm-files.

To moved the data by copying everything to an other machine and back, but
I do not remember the details how this happened. So I wasn't able to track =
the
problem down to it's cause yet. :-(

The corruption doesn't concerned the filesize in this case.

This happened on SuSE Linux 9.2 i686, maybe x86_64 too. I used the default
rsync that came with SuSE 9.2:

rsync version 2.6.3pre1 protocol version 28

I'm going to have a look at that now :-/
