    Update to dhcpcd-9.1.2 with the following changes:
    
     * BSD: Only mark static routes from dhcpcd.conf as static
     * DHCP6: Ensure requested addresses are requested
     * DHCP6: Fix prefix length calculation when no prefix specified
    
     * privsep: Implement a resource limited sandbox
    
    You will see a control proxy process now.
    This is for the resource limited sandbox so that we can isolate
    requests over the control socket.
    For NetBSD, FreeBSD and derivatives such as DragonFlyBSD this is a massive win
    as these OS now enjoy a similar level of protection as Capsicum or Pledge,
    but without the syscall filtering.
