Fedora 34 Aims To Further Enhance Security But Will Lose Runtime Disabling Of SELinux
With the release of Fedora 34, the popular Linux distro aims to further increase security by removing support for the disabling of SELinux at run-time.
Currently on Fedora the Security Enhanced Linux (SELinux) functionality that's there by default can be disabled at run-time via the /etc/selinux/config but moving forward with Fedora 34 they are looking at removing that support and focusing just on disabling via selinux=0 at the kernel boot time in order to provide greater security.
At present on Fedora, those wanting to forego the security safeguards can either pass selinux=0 as the kernel command line option to disable the support at boot time or by disabling it within the /etc/selinux/config file that in turn disables the support at run-time.
