Na vers\u00e3o Fedora 38, foi proposto implementar a primeira fase de transi\u00e7\u00e3o para um processo de inicializa\u00e7\u00e3o modernizado, anteriormente sugerido por Lennart Poettering, para estabelecer uma inicializa\u00e7\u00e3o verificada e abrangente que inclua todas as etapas, desde o firmware at\u00e9 o espa\u00e7o do usu\u00e1rio, e n\u00e3o apenas o n\u00facleo e o carregador. A proposta ainda n\u00e3o foi analisada pelo comit\u00ea FESCo (Fedora Engineering Steering Committee), respons\u00e1vel pela parte t\u00e9cnica do desenvolvimento da distribui\u00e7\u00e3o Fedora. <\/p>\n

Os componentes para a implementa\u00e7\u00e3o da ideia proposta j\u00e1 est\u00e3o integrados ao systemd 252 e consistem no uso, em vez da imagem initrd, gerada localmente no sistema durante a instala\u00e7\u00e3o do pacote com o n\u00facleo, de uma imagem unificada de n\u00facleo UKI (Unified Kernel Image), gerada na infraestrutura da distribui\u00e7\u00e3o e assinada digitalmente. O UKI combina em um \u00fanico arquivo o manipulador para carregar o n\u00facleo a partir do UEFI (UEFI boot stub), a imagem do n\u00facleo Linux e o ambiente de sistema inicializ\u00e1vel initrd. Ao invocar a imagem UKI a partir do UEFI, \u00e9 oferecida a possibilidade de verificar a integridade e autenticidade por meio da assinatura digital, n\u00e3o apenas do n\u00facleo, mas tamb\u00e9m do conte\u00fado do initrd, cuja verifica\u00e7\u00e3o \u00e9 importante, pois nesse ambiente \u00e9 realizada a extra\u00e7\u00e3o das chaves para descriptografar o sistema de arquivos raiz. <\/p>\n

Devido \u00e0s mudan\u00e7as significativas por vir, a implementa\u00e7\u00e3o est\u00e1 prevista para ser dividida em v\u00e1rias fases. Na primeira fase, o suporte ao UKI ser\u00e1 adicionado ao carregador, e come\u00e7ar\u00e1 a publica\u00e7\u00e3o de uma imagem opcional do UKI, que ser\u00e1 focada na inicializa\u00e7\u00e3o m\u00e1quinas virtuais<\/a> com um conjunto limitado de componentes e drivers, al\u00e9m das ferramentas relacionadas \u00e0 instala\u00e7\u00e3o e atualiza\u00e7\u00e3o do UKI. Nas segunda e terceira fases, est\u00e1 previsto deixar de passar configura\u00e7\u00f5es na linha de comando do n\u00facleo e cessar o armazenamento das chaves no initrd.
