Thanks for the suggestions!  I will surely try when I get the chance.

I am now in a different partition/installation that I don't want to mess up.

I want to be able to build packages besides and beyond lang/python38.

When was this entropy issue introduced (what NetBSD version)?

Does any other OS have such an entropy issue?

On the other computer, I am now on FreeBSD-current mass-building packages with synth.

Another old bug has popped up that I thought was fixed some time ago for NetBSD-current and releng-9:

I have to go into the debugger (Ctrl-Alt-Esc) if I can and reboot, otherwise Reset button.
