+  * Updated to CentOS Linux release 8.3.2011
+  * Booting into new kernel kept failing
+    * complained /boot ext4 filesystem was unknown
+  * Booted into previous kernel OK
+  * Did "rpm -qa |grep kernel | sort" and looked for all the latest versions
+  kernel-4.18.0-240.1.1.el8_3.x86_64
+  kernel-core-4.18.0-240.1.1.el8_3.x86_64

+Then reinstalled all of them using:
+  dnf reinstall kernel-4.18.0-240.1.1.el8_3.x86_64 kernel-core-4.18.0-240.1.1.el8_3.x86_64 kernel-devel-4.18.0-240.1.1.el8_3.x86_64 kernel-headers-4.18.0-240.1.1.el8_3.x86_64 kernel-modules-4.18.0-240.1.1.el8_3.x86_64 kernel-modules-extra-4.18.0-240.1.1.el8_3.x86_64 kernel-tools-4.18.0-240.1.1.el8_3.x86_64 kernel-tools-libs-4.18.0-240.1.1.el8_3.x86_64
+Rebooted into new kernel, working OK.
+__15 October 2020__
+  * For centos8-vtatdb2-l, selinux seems to have gotten messed up
+    * Tried a new VM by cloning centos8-minimal and immediately disabling selinux, rebooting
+  * mod_security was giving httpd errors and permission denied
+    * Try disabling this and then testing httpd stuff
