| 2 | # which initializes IMA by loading a policy before transferring |
| 3 | # control to the init process in the rootfs. The advantage over having |
| 4 | # that init process doing the policy loading (which systemd could do) |
| 5 | # is that already the integrity of the init binary itself will be |
| 6 | # checked by the kernel. |
