Indeed. In my script I had added the remote for the rcu git archive, but 
forgot to actually fetch the objects and refs, and missed the error 
message in the output.

Sorry for the noise, though the variable name should probably 
namespaced, as at least for the name `KVM` the chance are higher (still 
very small) that it’s set in the environment.


Kind regards,

Paul
