5.3 To load policy

If you modify policy in simplified_policy, you must load the modified policy to kernel. There are some targets in Makefile.
First, you have to go /etc/selinux/seedit/src/policy.

• make reload
  This converts simplified policy in simplified_policy dir into SELinux policy.
  (1) policy.conf and file_contexts are generated in sepolicy dir.
  (2) binary policy is created by checkpolicy from generated policy.conf.
  (3) binary policy is installed in /etc/seedit/policy, file_contexts is installed in /etc/seedit/contexts/policy. And contents of base_policy/contexts is installed in /etc/seedit/contexts.
  (4) binary policy is loaded by load_policy
• make relabel
  After make reload, fixfiles restore runs.

• make diffrelabel
  This is very useful. make relabel relabels all files, and it takes a lot of time. On the other hand, make diffrelabel relabels only files whose label have changed. So it takes only some seconds. When you load policy, make diffrelabel is recommended.
