SECCOMP — Enable seccomp to safely compute untrusted bytecode

This kernel feature is useful for number-crunching applications that may need to compute untrusted bytecode during their execution. By using pipes or other transports made available to the process as file descriptors supporting the read/write syscalls, it's possible to isolate those applications in their own address space using seccomp. Once seccomp is enabled via /proc/pid/seccomp, it cannot be disabled and the task is allowed to execute only a few safe syscalls defined by each seccomp mode.

If you are unsure, say yes. Only embedded systems should be built by answering no.
