Heiko, All,

I think it would be easier to just copy the file.

Also, /etc/os-release may not exist, in which case we should look to the
preferred locaiton, /usr/lib/os-release, something along the lines of:

    def get_os_release_path():
        for p in ['/etc/os-release', '/usr/lib/os-release']:
            if os.path.exists(p):
                return p
        return None

    def save_host_distro_info():
        [blurb]
        host_distro = os.path.join(self.resultdir, "host-distro")
        os_release = get_os_release_path()
        if os_release is None:
            with open(host_distro, "w") as f:
                f.write('Unknown')
        else:
            shutil.copyfile(so_release, host_distro)

Otherwise, if you have a good argument against the copy and to keep only
PRETTY_NAME, see below...

Could you find an english version, please? My german (the very little I
ever had) is a bit rusted... ;-]

I guess we would use that one, instead:
    https://manpages.debian.org/buster/systemd/os-release.5.en.html

You should probably anchor PRETTY_NAME at the beginning of the line,
