+ <title>Incompatibility with Auditing</title>

+ <para>Note that the kernel auditing subsystem is
+ currently broken when used together with
+ containers. We hence recommend turning it off entirely
+ by booting with <literal>audit=0</literal> on the
+ kernel command line, or by turning it off at kernel
+ build time. If auditing is enabled in the kernel
+ operating systems booted in an nspawn container might
+ refuse log-in attempts.</para>
