This selects the Simplified Mandatory Access Control Kernel.

Smack is useful for sensitivity, integrity, and a variety
|
of other mandatory security schemes.

Enable the bring-up ("b") access mode in Smack rules.
|
When access is granted by a rule with the "b" mode a
|
message about the access requested is generated. The
|
intention is that a process can be granted a wide set
|
of access initially with the bringup mode set on the
|
rules. The developer can use the information to
|
identify which rules are necessary and what accesses
|
may be inappropriate. The developer can reduce the
|
access rule set once the behavior is well understood.
|
This is a superior mechanism to the oft abused
|
"permissive" mode of other systems.

If you are unsure how to answer this question, answer N.

help
|
Sending a signal has been treated as a write operation to the
|
receiving process. If this option is selected, the delivery
|
will be an append operation instead. This makes it possible
|
to differentiate between delivering a network packet and
|
delivering a signal in the Smack rules.
