I would like to log the commandline with which parted is executed in

initialize-partition-table in gnu/build/vm.scm, but I do not know

where all the output is going. Apparently it is nowhere in the logs.

I was wrong; grub-mkrescue in gnu/build/vm.scm creates the ISO9660

partition table, not parted. It appears I can get at its commandline

by reconfiguring with a modified grub package that raises an error

containing the commandline. I will try later.

This seems to be a duplicate of https://issues.guix.info/issue/33639

, I think, but it happens to me on x86_64.
