If disabled via this mechanism, SELinux will remain disabled until the system is rebooted. The preferred method of disabling SELinux is via the "selinux=0" boot parameter, but the selinuxfs "disable" node was created to make it easier for systems with primitive bootloaders that did not allow for easy modification of the kernel command line. Unfortunately, allowing for SELinux to be disabled at runtime makes it difficult to secure the kernel's LSM hooks using the "__ro_after_init" feature. Thankfully, the need for the SELinux runtime disable appears to be gone, the default Kconfig configuration disables this selinuxfs node, and only one of the major distributions, Fedora, supports disabling SELinux at runtime. Fedora is in the process of removing the selinuxfs "disable" node and once that is complete we will start the slow process of removing this code from the kernel.
