Here is better evidence. Just now I ran the experiment using same kernel version, 4.19.42, as in the xenial experiment reported above. My conclusions are unchanged. The newly-introduced incompatible and inconsistent behavior depends on the modprobe release, not on the kernel release. I knew this

I have conducted more investigation into the cause, resulting in a significant restatement of the issue. As far as this bug is concerned, it appears there has been no regression, indeed no change in behavior in ifconfig (net-tools package) or ifup (ifupdown package). However it could be argued th

Can you please transfer this to the ifupdown package? Or should I just resubmit it from scratch? The discussions of the importance of ifconfig are beside the point. The problem presented itself during boot-up, in connection with an "auto dummy0" directive in /etc/network/interfaces. If "auto dummy

Here's an even simpler argument why random-seed-load and random-seed-save should be seen as two separate stateless services, not as the "start" and "stop" of some single long-lived service. Suppose that during boot-up, random-seed-load fails for some reason. There are definitely ways this could
