[ydl-gen] How to exclude packages?

[ulrich]

I have a problem to exclude some packages from the "yum update" cmd.
1.  how do I determine a package name? For instance "openoffice*"
or "openoffice\*" did not work did not work with me.
2. Can anybody please give me a sample comd-line?

N.B. I also tried to unmount devices with programmes to be excluded from
updates. Even this did _not_ work ....
