What are the files with the ".O" extension in /etc/cups/ppd and /var/log/cups?
Issue
We want to know what the duplicate files with .O suffixed mean. For example:
$ ls /etc/cups/ppd
-rw-r--r--. 1 root lp 9912 Jan 5 12:56 prt1.ppd
-rw-r--r--. 1 root lp 9878 Jan 5 12:51 prt1.ppd.O
-rw-r--r--. 1 root lp 1311 Jan 6 15:21 prt2.ppd
-rw-r--r--. 1 root lp 1311 Jan 6 15:24 prt2.ppd.O
