I've just checked with a Debian maintainer: /etc/os-release exists on stable, 
but not on older versions.

I will probably have to write a fallback to /etc/lsb-release. However, note 
that the file does not exist unless you've installed the LSB support package, 
which isn't the case for everyone.

I'm loathe to start scanning /etc for the version. That's why /etc/os-release 
is important.

If that file is not found, the version will be detected as "linux_<kernel-
version-here>".

The naming comes from me.
