Normally, upper tools and scripts are checking if we want to modify the
running kernel but not always. Check install and remove operation that
affect the running kernel to avoid possible issues.
Tested with Fedora 38, Fedora 39, RHEL 9, Oracle Linux 9.3,
openSUSE Tumbleweed and openMandrive ROME, using dnf/zypper and rpm tools.
