Subject: Changing unlabeled_t on files to invalid_label_t.

We would like to change

sid file_labels         gen_context(system_u:object_r:unlabeled_t,s0)

to something like

sid file_labels         gen_context(system_u:object_r:invalid_label_t,s0)

Since explaining to someone that a file without a label is file_t, but if it
has a label that the kernel does not understand it is labeled as unlabeled_t.
A file with a label is unlabeled_t????  While a file without a label is file_t.


#
# unlabeled_t is the type of unlabeled objects.
# Objects that have no known labeling information or that
# have labels that are no longer valid are treated as having this type.
#

#
# file_t is the default type of a file that has not yet been
# assigned an extended attribute (EA) value (when using a filesystem
# that supports EAs).
#

These two type definitions seem to conflict, with file_t winning at least on
systems that support XAttrs.

I would guess a better fix would be to change the kernel to handle the case
where an object is unlabeled_t one way and if it is labeled and the kernel
does not understand the label differently.

sid invalid_file_labels gen_context(system_u:object_r:invalid_label_t,s0)

Opinions....
