+ <item><file>/run</file> is allowed as an exception to the FHS and
+ replaces <file>/var/run</file>. <file>/run/lock</file>
+ replaces <file>/var/lock</file>. The FHS requirements for the older
+ directories apply to these directories as well. Backward compatibility
+ links will be maintained and packages need not switch to
+ referencing <file>/run</file> directly yet. Files in <file>/run</file>
+ should be stored in a temporary file system.

+ <item>New section spelling out the requirements for packages that use
+ files in <file>/run</file>, <file>/var/run</file>,
+ or <file>/var/lock</file>. This generalizes information previously only
+ in 9.3.2.
