John Seager, vice-presidente da Canonical respons\u00e1vel pela engenharia e l\u00edder t\u00e9cnico do projeto Ubuntu, anunciou a retomada do trabalho no projeto Ubuntu Core Desktop, que desenvolve uma edi\u00e7\u00e3o de desktop alternativa do Ubuntu, utilizando tecnologias da plataforma Ubuntu Core e empregando pacotes no formato Snap em vez de pacotes deb.<\/p>\n
Ao contr\u00e1rio dos atuais distribui\u00e7\u00f5es que s\u00e3o atualizadas atomicamente, cujos componentes do sistema s\u00e3o montados em modo apenas leitura, o Ubuntu Core Desktop adota um modelo em que 'todos os componentes est\u00e3o no formato snap'. Ao utilizar esse modelo, o conte\u00fado do ambiente do sistema, o n\u00facleo Linux, o carregador de inicializa\u00e7\u00e3o, os ambientes de desktop, servidores multim\u00eddia, processos em segundo plano e aplicativos s\u00e3o fornecidos no formato snap e gerenciados pela ferramenta snapd. <\/p>\n
Diferente do prot\u00f3tipo anteriormente desenvolvido, a distribui\u00e7\u00e3o pretende ser mais modular e, em vez de fornecer um \u00fanico pacote snap com o ambiente de sistema Ubuntu Core, dividir o sistema base em um conjunto de pacotes snap que podem ser atualizados separadamente. Todos os aplicativos ser\u00e3o executados com isolamento do sistema principal, e para pacotes que n\u00e3o suportam isolamento, ser\u00e1 fornecida uma camada para execu\u00e7\u00e3o utilizando virtualiza\u00e7\u00e3o.<\/p>\n
Para controlar o acesso dos aplicativos a recursos do sistema e externos, est\u00e1 em desenvolvimento um mecanismo de solicita\u00e7\u00e3o de permiss\u00f5es, que requer a confirma\u00e7\u00e3o do usu\u00e1rio para o acesso, por exemplo, ao acessar arquivos no diret\u00f3rio pessoal, \u00e0 c\u00e2mera ou ao microfone a partir de pacotes snap. A exibi\u00e7\u00e3o din\u00e2mica das solicita\u00e7\u00f5es \u00e9 feita com base na an\u00e1lise das chamadas de sistema, e o controle de acesso \u00e9 organizado usando o AppArmor. <\/p>\n
O desenvolvimento est\u00e1 focado em tr\u00eas cen\u00e1rios b\u00e1sicos de uso:<\/p>\n
Durante a prepara\u00e7\u00e3o do pr\u00f3ximo lan\u00e7amento do Ubuntu, est\u00e1 prevista a separa\u00e7\u00e3o dos componentes do ambiente de desktop em diferentes m\u00f3dulos, a forma\u00e7\u00e3o de interfaces snap para suportar diferentes fun\u00e7\u00f5es e cen\u00e1rios de uso do desktop, al\u00e9m de testar a nova arquitetura do Ubuntu Core Desktop nos tr\u00eas cen\u00e1rios de uso mencionados. Al\u00e9m disso, em colabora\u00e7\u00e3o com os desenvolvedores do projeto KDE Neon, come\u00e7ou a ser trabalhado em uma variante da distribui\u00e7\u00e3o KDE Neon, implementada sobre o Ubuntu Core, o que permitir\u00e1 adaptar o Ubuntu Core Desktop para suportar diferentes ambientes de desktop, n\u00e3o se limitando ao GNOME. \u0414\u0436\u043e\u043d \u0421\u0438\u0433\u0435\u0440 (Jon
