 The test also requires loaded policy with `func=KEY_CHECK`, see example in `keycheck.policy`.
 
+### IMA kexec test
+
+This test requires that the ima policy contains:
+```
+measure func=KEXEC_CMDLINE
+```
+
+Even though the test does not actually reboot, it does require a valid,
+signed kernel image. By default, the test will look in `/boot/vmlinuz-$(uname r)`,
+but if no image is accessible there, a valid image be must be placed at `/tmp/Image`.

 ## EVM tests
 
 `evm_overlay.sh` requires a builtin IMA appraise tcb policy (e.g. `ima_policy=appraise_tcb`
