DESCRIPTION:We are working on a new scheme to replace the GRUB bootloader w
 ith a fast\, secure\, Linux-based\, user-space solution: nmbl (for no more
  boot loader).\nMost people are familiar with GRUB\, a powerful\, flexible
 \, fully-featured bootloader that is used on multiple architectures (x86_6
 4\, aarch64\, ppc64le OpenFirmware). Although GRUB is quite versatile and 
 capable\, its features create complexity that is difficult to maintain\, a
 nd that both duplicate and lag behind the Linux kernel while also creating
  numerous security holes. On the other hand\, the Linux kernel\, which has
  a large developer base\, benefits from fast feature development\, quick r
 esponses to vulnerabilities and greater overall scrutiny.\nWe (Red Hat boo
 t loader engineering) will present our solution to this problem\, which is
  to use the Linux kernel as its own bootloader. Loaded by the EFI stub on 
 UEFI\, and packed into a unified kernel image (UKI)\, the kernel\, initram
 fs\, and kernel command line\, contain everything they need to reach the f
 inal boot target. All necessary drivers\, filesystem support\, and network
 ing are already built in and code duplication is avoided. \nWe will showca
 se the work done so far\, and ask you for your feedback and use cases.
