1665           This kernel feature is useful for number crunching applications
1666           that may need to compute untrusted bytecode during their
1667           execution. By using pipes or other transports made available to
1668           the process as file descriptors supporting the read/write
1669           syscalls, it's possible to isolate those applications in
1670           their own address space using seccomp. Once seccomp is
1671           enabled via /proc/<pid>/seccomp, it cannot be disabled
1672           and the task is only allowed to execute a few safe syscalls
1673           defined by each seccomp mode.
1674
1675           If unsure, say Y. Only embedded should say N here.
