How is the libc issue specific to linux? OpenBSD has a libc too.

OpenBSD doesn't support syscalls from alternative libcs, so you reliably get consistent syscall behavior.

But I believe GP is mostly talking about pledge(2), a pretty easy way to implement common sets of seccomp-like restrictions, and unveil(2), an easy way to limit path visibility. These are OpenBSD security features that Linux does not have direct equivalents of.
