BTW,

From reboot code in dhcpcd.c:
void
start_reboot(struct interface *iface)
{
        struct if_options *ifo = iface->state->options;

        if (ifo->options & DHCPCD_LINK && iface->carrier == LINK_DOWN) {
                syslog(LOG_INFO, "%s: waiting for carrier", iface->name);
                return;
        }
        if (ifo->options & DHCPCD_STATIC) {
                start_static(iface);
                return;
        }
        if (ifo->reboot == 0 || iface->state->offer == NULL) {
                start_discover(iface);
                return;
        }
....

seems like dhcpcd/if-options.c has the following:
        case 'y':
                ifo->reboot = atoint(arg);
                if (ifo->reboot < 0) {
                        syslog(LOG_ERR, "reboot must be a positive value");
                        return -1;
                }
                break;


Does it make sense to add -y1 to dhcocd cmd line args to force discover
after reboot?

Thanks,
