This option will be useful for systems where 48 operations which can lead to the hijacking of the boot sequence are 49 needed before loading the policy. For example, you can activate 50 immediately after loading the fixed part of policy which will allow 51 only operations needed for mounting a partition which contains the 52 variant part of policy and verifying (e.g. running GPG check) and 53 loading the variant part of policy. Since you can start using 54 enforcing mode from the beginning, you can reduce the possibility of 55 hijacking the boot sequence. 56 57config SECURITY_TOMOYO_POLICY_LOADER 58 string "Location of userspace policy loader" 59 default "/sbin/tomoyo-init" 60 depends on SECURITY_TOMOYO 61 depends on !SECURITY_TOMOYO_OMIT_USERSPACE_LOADER 62 ---help--- 63 This is the default pathname of policy loader which is called before 64 activation.
