<para>&os; provides binary compatibility with &linux;, allowing
users to install and run &linux; binaries on a &os; system.
Many companies and developers develop only for &linux;, and
binary compatibility allows &os; users to run about 90% of all
&linux; applications without modification. This includes
productivity applications, games, and more. It has even been
reported that, in some situations, &linux; binaries perform

better on &os; than they do on &linux;.</para>
<para>However, some &linux;-specific operating system features
