Yeah, it looks closer to 5 old kernels.
#!/usr/bin/env bash
mapfile -t old_kernels < <(dnf repoquery --installonly --latest-limit=-2 -q)
if [ "${#old_kernels[@]}" -eq 0 ]; then
echo "No old kernels found"
clean_lib_modules
exit 0

if ! dnf -y remove "${old_kernels[@]}"; then
echo "Failed to remove old kernels"
exit 1
