Thanks a lot.
Now it seems so obvious to me, but I really wouldn't have thought about 
this little detail :)

I can confirm this is working.

Do you have any more info on this?
Except from poudriere's man page's description I could find no other 
docs. Is there any more elaborate description on what this does and how?

I built the jail with -x, but how do I check it's using "native-xtools"?

I tried building ports-mgmt/pkg and it requires ten times more than 
native build (i.e. 24 minutes for aarch64 vs. less than 3 minutes for 
amd64). Is this normal?



  bye & Thanks
