I now see that this was expected:

exit_unless_last_interface() {
    ifaces="$(ifquery --list)"
    for i in $ifaces ; do
        if [ "$i" = "lo" ]; then
            continue
        fi
        if ! ifquery --state $i >/dev/null ; then
            msg="if-up.d/mountnfs[$IFACE]: waiting for interface $i before doing NFS mounts"
            log_warning_msg "$msg"
            exit 0
        fi
    done
}

    # Wait until all auto interfaces are up before attempting to mount
    # network file systems.
    exit_unless_last_interface

I thought that this caused a slowdown of the boot, as there were
a delay of several seconds after this log message. But it was
probably unrelated.

I do not use sysvinit any longer (on any machine). But note that the
above logic might be wrong since "auto" is not the only way to bring
interfaces up. Later, I used netplugd (from the netplug package).
There was also allow-hotplug (which was not existing yet when I had
initially installed the machine).
