That seems to take care of the logread problem. Thanks.

But neither collectd not nlbwmon starts. They are still broken with the 
current ubus.


Looking now at the (again working) system log reveals:

root at router2:~# logread | grep collectd
Fri Dec 27 16:23:37 2019 daemon.info procd: Not starting instance 
collectd::instance1, command not set
root at router2:~# logread | grep nlbwmon
Fri Dec 27 16:23:33 2019 daemon.info procd: Not starting instance 
nlbwmon::instance1, command not set
