Hey Ludo,
> But I think the problem should show up even with “make check-system > TESTS=installed-os” on master. Well this does not involve the graphical installer, so I'm not sure to understand. Anyway, testing the installer in Qemu, I can reproduce a failure where the first umount in "umount-cow-store" throws an exception (busy device), when umounting a crypted partition. That's probably what's bitting you, so to be continued! Thanks, Mathieu
