Description of problem:
After yum update of samba there is no new configuration file as well as there is no rpmsave back up file of the configuration file. There was difference in smb.conf file so it is expected to keep a back up and create a new file.

Version-Release number of selected component (if applicable):
samba 4.2.4
glusterfs-server-3.7.1-16.el7rhgs.x86_64

How reproducible:
Always

Steps to Reproduce:
1.On samba 4.1 create a share on smb.conf
2.yum update
3.ls -l /etc/samba

Actual results:
No new smb configuration file and no rpmsave of configuration file is present

Expected results:
As there is a difference is configuration file so after yum update smb.conf.rpmsave file should be present along with new smb.conf.
