This patch adds support for using the last path component as part of the information in making labeling decisions for new objects. A example rule looks like so: type_transition unconfined_t etc_t:file system_conf_t eric; This rule says if unconfined_t creates a file in a directory labeled etc_t and the last path component is "eric" (no globbing, no matching magic, just exact strcmp) it should be labeled system_conf_t. The kernel and policy representation does not have support for such rules in conditionals, and thus policy explicitly notes that fact if such a rule is added to a conditional.
