Hello everyone

I have a fresh centos 7 installation which I would like to setup as a print server. I downloaded latest cups version 2.2.5, extracted the file and then simply followed the
instructions on the INSTALL.md file. All did was

./configure
make
make install

There were no errors during the installation. I have 2 questions:

1. Why I can not see cups version 2.2.5 installed when I do
Code:
rpm -qa cups
? Is that because it wasn't an rpm pacakge?
2. Inside /etc/cups I can see the following files:

Code:
-rw-------. 1 root lp      0 Aug  3 19:41 classes.conf
-rw-r--r--. 1 root lp      0 Aug  3 19:41 client.conf

-rw-r-----. 1 root lp    408 Oct 18 14:35 subscriptions.conf.O
The files with dated 19th October were created after the installation of cups 2.2.5. To start using cups2.2.5. I presume all I have to do is rename:

cupsd.conf.N --> cupsd.conf
cups-files.conf.N --> cups-files.conf
snmp.conf.N--> snmp.conf

Would that be the right procedure? Is there anything else I should consider?

Many thanks
