Hi,

many of my systems did not upgrade from 7.3 to 7.4 with "yum update"
although yum-conf-sl7x is installed and I did run "yum clean
expire-headers". Somehow "7.3" entered /etc/yum/var/slrelease instead of
"7x". The time of this change is the time of the previous upgrade from
7.2 to 7.3.

> [root@vm483 ~]# ls -l /etc/yum/vars/slreleasever 
> -rw-r--r--. 1 root root 4 26. Jan 2017  /etc/yum/vars/slreleasever

> [root@vm483 ~]# cat /etc/yum/vars/slreleasever
> 7.3

> [root@vm483 ~]# rpm -Vvl yum-conf-sl7x
> .........    /etc/yum/vars/releasever
> S.5......    /etc/yum/vars/slreleasever

> [root@vm483 ~]# grep yum-conf /var/log/yum.log*
> /var/log/yum.log:Jan 10 06:18:32 Aktualisiert: yum-conf-sl7x.noarch 7.2-4.sl7
> /var/log/yum.log:Jan 26 08:47:12 Aktualisiert: yum-conf-sl7x.noarch 7.3-4.sl7

After running "yum reinstall yum-conf-sl7x" /etc/yum/vars/slreleasever
is OK again and "yum update" did the shift to 7.4. However, after this
upgrade /etc/yum/vars/slreleasever again contains the point release –
now 7.4.

> [root@vm001 ~]# cat /etc/yum/vars/slreleasever 
> 7.4
> [root@vm001 ~]# rpm -Vvl yum-conf-sl7x
> .........    /etc/yum/vars/releasever
> S.5......    /etc/yum/vars/slreleasever

How is it meant to work?
Is the preuninstall script intended?
