thanks for the answer & sorry for the delay. That was clear to me, maybe my question was inprecise: If I understand the check* targets right, there is the general purpose target "check" which can be run as a non-root or a root user while there is a special target for root-only checks named "check-root". If this is true, then why is a non-root made during "check-root"? Have a nice day, Berny
