There should not be any default_t directories. Thus this shouldnt be
allowed.

This stems from the fact that at some point I came to a state where
while working from the terminal (as opposed to working from a graphical
terminal), semanage had trouble dealing with some temporary local
modules that I was working with for testing purposes (they were labelled
default_t)...
Of course it can be removed. So, in general default_t should never
appear anywhere in the policy ? Just for curiosity, what is the reason
behind that ? If it is allowed to carry out operations on usr and
etc_runtime files, why shouldn't it allowed to carry out operations on
default_t ?
Regards,
Guido

locations unknown to selinux are labelled default_t. So for example if
you create a dir named /test in the root of the filesystem. There is no
file context specification for it and thus selinux labels it default_t.
Basically it signals some incompatibility in that sense because files
always need a label, and this should not happen.
Why should refpolicy support a scenario that should never happen in the
first place? default_t is not like other types like usr_t or
etc_runtime_t. types like file_t, default_t, unlabeled_t all signal some
other issues. I think this is discussed in "Fedora SELinux user guide"
(you can find it with google, its a free document.
