In the %post scriptlet[1]:

%post
for v in %{selinux_variants}; do
	/usr/sbin/semodule -s $v \
		-i %{_datadir}/selinux/$v/%{semodule_name}.pp >&- 2>&- || :
done
/sbin/restorecon -R %{basedir} || :

I changed the output redirection to send to a log, and I see this error
message:

/usr/sbin/semodule: SELinux policy is not managed or store cannot be
accessed.
