pretalx.comNo more boot loader: Please use the kernel instead DevConf.CZWe are working on a new scheme to replace the GRUB bootloader with a fast, secure, Linux-based, user-space solution: nmbl (for no more boot loader). Most people are familiar with GRUB, a powerful, flexible, fully-featured bootloader that is used on multiple architectures (x86_64, aarch64, ppc64le OpenFirmware). Although GRUB is quite versatile and capable, its features create complexity that is difficult to maintain, and 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 responses to vulnerabilities and greater overall scrutiny. We (Red Hat boot 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, initramfs, and kernel command line, contain everything they need to reach the final boot target. All necessary drivers, filesystem support, and networking are already built in and code duplication is avoided. We will showcase the work done so far, and ask you for your feedback and use cases.

@nixCraft This just sounds like a classic case of Red Hat coming up with a solution in search of a problem and then pushing it on other distributions. That's not anything new.

You can already jump from UEFI to the Linux kernel without GRUB. That has been a solved problem for a long time.

@hexaheximal @nixCraft Ah, so you didn't actually look into what nmbl did just had to leave a comment to sound intelligent.

@ljrk @nixCraft No, I've been aware of these linux-based bootloaders for a long time and I've used them before too. It's just not very practical.

Your response is very clearly ragebait, so I'm just going to block you before this goes any further - you're not acting in good faith and this isn't going to result in a productive conversation.
