Problem with SELinux while being attached through lxd-agent
by doskanoness from LinuxQuestions.org on (#5S86W)
Hey, I'm going to prepare a hardened SELinux virtual machine for the LXD with Gentoo. I have a problem with the message
Code:!!! Failed to set new SELinux execution context. Is your current SELinux context allowed to run Portage?when I emerge whatever package:
Code:gentoo-hardened-selinux-nomultilib ~ # emerge -NuDav @world
