@zekjur I do the module block with the install rule; but I think the most elegant is what Debian sysadmin team does: https://salsa.debian.org/dsa-team/mirror/dsa-puppet/-/blob/production/modules/debian_org/templates/rc.local.erb?ref_type=heads/etc/rc.local (which runs at boot if systemd/init hooks it, do check that):sleep 60echo 1 > /proc/sys/kernel/modules_disabledThus after the first minute of boot, disable any further module loading.Works on kernels and for modules that one does not use. Thus Debian is fine, RHEL is not for this class of bugs.(and one can 0 it if need to load a mod)
