Fwd: RFR (S) 8154566: os_linux.cpp parse_os_info gives non descriptive output on current SLES releases

[Gerald Thornbrugh]

Hi Coleen,

It looks like /etc/SuSE-release is deprecated starting with SLE 12 and 
will be removed in the future.

See:

https://www.suse.com/releasenotes/x86_64/SUSE-SLED/12/

So once the /etc/SuSE-release is removed it looks like the code will 
find the /etc/lsb-release file again and
this problem may come back unless I am not understanding this correctly.

I wonder if the /etc/os-release file should be moved before the 
/etc/lsb-release file in the list?

Understanding the implications of that change would take a significant 
amount of testing.
