When uninstalling some overlaid packages, I got shown:
Inactive requests:
nano (already provided by nano-4.9.3-1.fc32.x86_64)
fedora-toolbox (already provided by toolbox-0.0.95-1.fc32.x86_64)
So at some point in the past (this is an old Silverblue install) I likely overlaid it. Showing such unfulfilable requests in rpm-ostree status
may help in such cases. Thanks.
