This release introduces 2 new features and a few small improvements on the test suite runner:

• Added user initrd configuration. User now can add their own initrd freestanding to /etc/kernel/initrd.d and also mask system's initrd by creating a symlink pointing to /dev/null;
• Added configuration to avoid touching efi variables, it's useful for dual-boot scenarios when a user wants to manually manage the efi entries;
