Hello,
When a producing a disk-image, the system derivations are built twice: --8<---------------cut here---------------start------------->8--- building /gnu/store/8w9ic3h26w6rp4pj94gd93lw2bnqywgm-system.drv... successfully built /gnu/store/8w9ic3h26w6rp4pj94gd93lw2bnqywgm-system.drv building /gnu/store/bxh7s2lwl82d3lwd59swkf243h17gyg1-system.drv... successfully built /gnu/store/bxh7s2lwl82d3lwd59swkf243h17gyg1-system.drv building /gnu/store/81wqilcd9g8c0yh6xj7chbla9agz06d9-grub.cfg.drv... successfully built /gnu/store/81wqilcd9g8c0yh6xj7chbla9agz06d9-grub.cfg.drv building /gnu/store/m87i36kdb09vig99q3mj24f30i1h8bjf-grub.cfg.drv... successfully built /gnu/store/m87i36kdb09vig99q3mj24f30i1h8bjf-grub.cfg.drv building /gnu/store/ngdkc4dhaf9qhry71dmcp1dj7rvnaqiy-partition.img.drv... --8<---------------cut here---------------end--------------->8--- The installed Grub configuration file in /boot/grub/grub.cfg points to a system that is *not* part of the closure. The second Grub configuration file shown above points to the other system that *is* part of the closure. While booting the image in QEMU, the boot fails when trying to access the missing /gnu/system/xxx-system/boot file. Thanks, Mathieu
