I've tried to reproduce this but failed. I'm using an amd64 stretch
install as a base, with a newly debootstrapped --arch=i386
--variant=minbase chroot where I installed mkosi build-deps, fetched
mkosi sources and ran debian/rules binary.
I've also tried to manually check return codes (0) and mkosi --help
output (stdout). Nothing peculiar noticed.

Suggestions on how I can reproduce the problem welcome.
