This is the default value for maximal ACL entries

Some programs access thousands of objects, so running

such programs in "learning mode" dulls the system response
|

and consumes much memory.

This is the safeguard for such programs.

Say Y here if you want to activate access control as soon as built-in
|
||
|
|
policy was loaded. This option will be useful for systems where
|
||
|
|
operations which can lead to the hijacking of the boot sequence are
|
||
|
|
needed before loading the policy. For example, you can activate
|
||
|
|
immediately after loading the fixed part of policy which will allow
|
||
|
|
only operations needed for mounting a partition which contains the
|
||
|
|
variant part of policy and verifying (e.g. running GPG check) and
|
||
|
|
loading the variant part of policy. Since you can start using
|
||
|
|
enforcing mode from the beginning, you can reduce the possibility of
|
||
|
|
hijacking the boot sequence.
