mkosi failed for me because part of the OS tree was deleted while creating the image:
The files created in /var/tmp/mkosi-* are older than 30 days. systemd-tmpfiles-clean.service started while I created the image and deleted most of the OS tree.
It seems to me, that /var/tmp is a bad choice for the temporary directory.
