Thanks.  Ludo already made that remark
    https://debbugs.gnu.org/cgi/bugreport.cgi?bug=55227#46

and it has been changed in the v3 patch series

    https://debbugs.gnu.org/cgi/bugreport.cgi?bug=55227#97

which has already been installed in core-updates.  The only puzzle that
remains is the coding of some of the native-inputs.

Right, same remark.

Yes, it's a simple/ancient machine from the 70s (?) I belief, and having
a working VM for Knight is/was one of the goals of the Stage0 project
(to eleminate the dependency on a kernel like Linux).

Thanks, I'll consider that.
