[$] Giving bootloaders the boot with nmbl

At DevConf.cz 2024,Marta Lewandowska gave a talk to discuss anew approach for booting Linux systems, "No more bootloader: Please use the kernel instead". The talk, available onYouTube, introduced a new project called nmbl (for "no more bootloader",pronounced "nimble"). The idea is to get rid of bootloaders (e.g., GNU GRUB) with aUnifiedKernel Image (UKI) that removes the need for a separate bootloaderaltogether. It is early days for nmbl, currently the project is onlybeing tested for use with virtual machines, but the idea iscompelling. If successful, nmbl could offer security, performance, andmaintenance benefits compared to GRUB and other separate bootloaders.
