Hi, Just my 2 cents on that: > VERSION_ID=unstable Already in an issue to base-files: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=931197 > VERSION_CODENAME=sid Does this have been/have-to-be reported to base-files? But regarding 'man os-release', they are both optional, isn't it? Regards, Patrice
