These are the steps I followed enable VirtualBox on my laptop without disabling UEFI Secure Boot. They're nearly identical to the process described on [Øyvind Stegard's blog][blog], save for a few key details. The images here are borrowed from the [Systemtap UEFI Secure Boot Wiki][systemtap].

Container Linux Configs can be used to format and attach additional filesystems to Container Linux nodes, whether such storage is provided by an underlying cloud platform, physical disk, SAN, or NAS system. This is done by specifying how partitions should be mounted in the config, and then using a systemd mount unit to mount the partition. By systemd convention, mount unit names derive from the target mount point, with interior slashes replaced by dashes, and the .mount extension appended. A unit mounting onto /var/www is thus named var-www.mount.
Mount units name the source filesystem and target mount point, and optionally the filesystem type. Systemd mounts filesystems defined in such units at boot time. The following example formats an EC2 ephemeral disk and then
