You're right, /etc/os-release being absent should not result in a
build failure. And instead of matching on ID specifically, we could
probably use something like

  grep -E '^ID(_LIKE)*=' /etc/os-release

instead and check only a subset of the strings we currently do. RHEL
and CentOS for example are both ID_LIKE=fedora. We'd have to be
careful about the order in which the Debian and Ubuntu branches
appear though.
