I don't know if the problem is in dnf, a database, or something/somewhere else. But post patching clean-up seems to be an ongoing problem. The script uses `du` to count the size of files in the directory tree of each [previously installed] kernel. If the size is less than 4K, it deletes the directory tree. If the size is greater than 4K, then it is not touched. Here's an example of what causes the accumulation of leftovers in /lib/modules from a Linux Mint machine. As I understand things, the kernel uses the same scripts everywhere. Notice the "dpkg: warning...". Removing linux-modules-5.15.0-122-generic (5.15.0-122.132) ... (Reading database ... 375164 files and directories currently installed.)
