That sound good to me. There seems to be a move in the community at 
large to support "/os-release".

         1. Announcement of /etc/os-release
            http://0pointer.de/blog/projects/os-release

         2. Common Platform Enumeration Specification
            http://cpe.mitre.org/specification/

         3. RFC3986 format
            https://tools.ietf.org/html/rfc3986


I tried the patch an it looks good.

many thanks,
Armin
