The file /etc/cups/lpoptions is not owned by any package.
Therefore it will not exist after CUPS package installation.

How to reproduce when /etc/cups/lpoptions does not exist:

root@host# umask 077

root@host# lpoptions -d queue

root@host# ls -l /etc/cups/lpoptions
-rw-------  1 root root ... /etc/cups/lpoptions

Now when a normal user runs "lpstat -d", he gets a wrong default queue.
There is no warning or error message when /etc/cups/lpoptions cannot be
read (see bug #118766).

Proposals for a solution:
Either the lpoptions command creates it with appropriate owner
and permissions or we should have an empty /etc/cups/lpoptions
in our RPM with the following permissions:  -rw-r--r--   lp lp

Note:
Normally YaST printer config creates it as
-rw-r--r--  1 root root 0 ... /etc/cups/lpoptions
when it runs at the end of the installation.
But I think it should work even without YaST.
