# Only init should be able to load SELinux policies. # Only init should be able to load SELinux policies and set enforcing mode.
# The first load technically occurs while still in the kernel domain, neverallow { domain -init } kernel:security { load_policy setenforce };
# but this does not trigger a denial since there is no policy yet.
# Policy reload requires allowing this to the init domain.

# Only init prior to switching context should be able to set enforcing mode.
# init starts in kernel domain and switches to init domain via setcon in
# the init.rc, so the setenforce occurs while still in kernel. After
# switching domains, there is never any need to setenforce again by init.
