+* The following kernel parameters are configured automatically: `fs.inotify.max_user_instances = 1024` and `fs.inotify.max_user_watches = 65536`.
+* Adds a preflight check to ensure the following kernel parameters are set correctly: `fs.inotify.max_user_instances = 1024` and `fs.inotify.max_user_watches = 65536`.
+* Surfaces better error messages during the installation if the node is not ready.
+* Adds a preflight check to verify execute permissions on the data directory and its parent directories. This prevents installation issues, including etcd permissions issues.

 * The following kernel parameters are configured automatically: `net.ipv4.conf.all.forwarding = 1`, `net.ipv4.conf.default.forwarding = 1`, `net.bridge.bridge-nf-call-iptables = 1`, `net.ipv4.conf.default.rp_filter = 0`, and `net.ipv4.conf.all.rp_filter = 0`.
 * The following kernel modules are configured automatically: `overlay`, `ip_tables`, `br_netfilter`, and `nf_conntrack`.
-* Adds a preflight check to ensure the values were set correctly for the `net.ipv4.conf.all.forwarding = 1`, `net.ipv4.conf.default.forwarding = 1`, `net.bridge.bridge-nf-call-iptables = 1`, `net.ipv4.conf.default.rp_filter = 0`, and `net.ipv4.conf.all.rp_filter = 0` kernel parameters.

 * Adds a preflight check to ensure the `overlay`, `ip_tables`, `br_netfilter`, and `nf_conntrack` kernel modules were configured correctly.
 * Adds a preflight check to ensure a node's IP address is not within the Pod and Service CIDR ranges that will be used by Kubernetes. If a conflict exists, a different CIDR block can be specified with `--cidr` or a different network interface can be specified with `--network-interface`.
 * Adds a preflight check to ensure that SELinux is not running in enforcing mode.
