By default, Linodes boot using a host-supplied kernel. SELinux support is not enabled in the Linode-supplied kernels, but you can compile your own kernel that supports it, as per this guide: ~~[http://library.linode.com/advanced/pv-grub-custom-compiled-kernel" target="_blank">](http://library.linode.com/advanced/pv-g … led-kernel">http://library.linode.com/advanced/pv-grub-custom-compiled-kernel](. Hope this information is helpful!
