OK, I've found that if I use a profile installing "scheme-context", then 
everything is OK, but if I use a profile using "scheme-infraonly" then 
"tlmgr install scheme-context", it doesn't!

Looking what the installation routine actually logs when using 
scheme-context from a profile, it says

     setting up ConTeXt cache: running mtxrun --generate ...done
     running context --luatex --generate ...done

and indeed if I use "scheme-infraonly", add in "context" then run those 
two commands, it works.

So the question is what the subtle difference is between installing 
"scheme-context" from a profile and from tlmgr.
