Message reads:

> Note: Incompatible Packages

>Some packages modify the contents of /var or /srv in their RPM %post scripts.
> These packages are incompatible. If you happen upon such package, file a bug report.

However "If you happen upon such package" seems a bit odd, I suggest that part
being changed to: "If you happen to find packages doing this..." or something
similar.
