Would that be something we could reasonably do?
This would result in the kernel package "owning" a file in /var/tmp
that doesn't exist. The name doesn't actually matter and the file
wouldn't actually be in the package. RPM would just ensure that
enough space would exist in /var/tmp before allowing the installation
to begin.
FWIW, the name does matter. You'd have to ensure the name is as unlikely
to collide with whatever anyone puts there as possible. Otherwise you
could get a user file removed when the kernel is removed, right?
