SuSE 10.0 uses taken uid/gid?

Hi, When trying to start the YaST2 User/Group Manager it complained that there were multiple uses of the same group id. In my case it was mysql and messagebus that conflicted. Fixing that and retrying it also complained about multiple uses of the same user id... dhcp and messagebus Doesn't messagebus install check if uid/gid is already taken? I do not think that I myself caused this problems, but I guess that this might be security related. /RogerL
