For me it looks like a timing issue. During boot several processes run in parallel and depending on whether a certain process A finishes before a certain process B rc-sysinit gets started or not. The timing can be influenced by whether a cold boot or a reboot is done and also by reinstalling packages as then files get placed on different locations on the disk and so the access can get faster or slower, But strange is that reinstalling CUPS causes any changes, because the problem happens before any file of CUPS gets touched.
