1.1.4.2 efivarfs

The Unified Extensible Firmware Interface (UEFI) variable file system (efivarfs) is enabled on systems that support UEFI. For Oracle Linux 7, systemd automatically mounts efivarfs. For Oracle Linux 6, efivarfs is not mounted by default. If required, you can mount efivarfs, for example:

# mount -t efivarfs efivarfs /sys/firmware/efi/efivars
