Hi All , Good Morning . I am following the SELINUX NOTEBOOK & trying the same at my end . - The refpolicy modules are copied at /usr/share/selinux/refpolicy i can see around 400+ modules there . But can senior member' s please help me understand how is the /etc/selinux/refpolicy/policy/policy.31 created using the modules available at /usr/share/selinux The command i followed : $ make install-src $ make conf $ make load ( tried even $ make install ) $ make install-headers - This can help me to debug an issue where i am trying to get selinux of my custom distro where all the make command are successfully executed but the policy.31 is not getting created - I can even see the "include" folder also getting created for make install-headers Any pointers will be helpful or please let me know if i am missing any aspect here . Thanks , Ashish.
