As shown, virt-manager is overlayed to fedora/33/x86_64/silverblue
When I want to overlay virt-manager to fedora/34/x86_64/silverblue again, I got the error:
Package/capability ‘virt-manager’ is already requested
Is there a way to overlay the same set of packages (if they are available to both) to two deployments of Silverbase having different base version?
