+ <listitem><para>A space-separated list

+ packaging and programming interfaces,
+ for example listing one or more
+ distribution identifiers the local
+ distribution is a derivative

+ <varname>ID=</varname> is not

+ be listed in order of how closely the
+ local operating system relates to the
+ listed ones, starting with the
+ closest. This field is
+ optional. Example: for an operating
+ system with
+ <literal>ID=centos</literal> an
+ assignment of <literal>ID_LIKE="rhel
