Thanks for the suggestions!  I decided to try option B, since I've done 
it before, and the others are more involved.  But I'm having trouble, 
and I'm not sure where I'm going wrong.

I've built (Nova) Sculpt ISO and IMG images several times, both from the 
"20.11" label and current master, and tested in VirtualBox and on AMD 
hardware, with the same results.

1. The "VERSION" file reports "20.09".

2. Trying to fetch some of the depots, including "genodelabs", looks for 
version "20.09", and results in "unavailable" errors.

Does anyone have any thoughts on this?
