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,
