This option will be useful for systems where 44 operations which can lead to the hijacking of the boot sequence are 45 needed before loading the policy. For example, you can activate 46 immediately after loading the fixed part of policy which will allow 47 only operations needed for mounting a partition which contains the 48 variant part of policy and verifying (e.g. running GPG check) and 49 loading the variant part of policy. Since you can start using 50 enforcing mode from the beginning, you can reduce the possibility of 51 hijacking the boot sequence. 52 53config SECURITY_TOMOYO_POLICY_LOADER 54 string "Location of userspace policy loader" 55 default "/sbin/tomoyo-init" 56 depends on SECURITY_TOMOYO 57 depends on !SECURITY_TOMOYO_OMIT_USERSPACE_LOADER 58 ---help--- 59 This is the default pathname of policy loader which is called before 60 activation.
