Case in point: I delete the goffice* and repodata folders from /mnt/openmediavault/kernel/results, but $ mock --chain --localrepo=/mnt/openmediavault/kernel -r fedora-34-x86_64 goffice/goffice-0.10.49-1.fc36.src.rpm gnumeric/gnumeric-1.12.49-1.fc36.src.rpm will keep working from the laptop as goffice-0.10.49 was never rebuilt from the desktop, but $ mock --chain --localrepo=/mnt/openmediavault/kernel -r fedora-34-x86_64 goffice/goffice-0.10.50-2.fc36.src.rpm gnumeric/gnumeric-1.12.50-2.fc36.src.rpm will fail when run from the laptop, even if the goffice-0.10.50-2.fc36 folder does not exist when the build is started.

What I do not really understand is that starting in an empty folder does not help. Does samba cache the permissions somewhere where they could survive the deletion of the file? Best regards, Julian
