Ressalta-se que a atribui\u00e7\u00e3o do n\u00famero 1.0 ap\u00f3s 21 anos de desenvolvimento marcou o reconhecimento da prontid\u00e3o do projeto e sua conformidade com as exig\u00eancias funcionais dos sistemas de inicializa\u00e7\u00e3o e gerenciadores de servi\u00e7os modernos.      <\/p>\n<p>O projeto \u00e9 desenvolvido por desenvolvedores da distribui\u00e7\u00e3o GNU Guix System como uma alternativa ao sistema de inicializa\u00e7\u00e3o SysV-init, suportando depend\u00eancias. O daemon gerenciador e as utilidades do Shepherd foram escritos na linguagem Guile (uma das implementa\u00e7\u00f5es da linguagem Scheme), que tamb\u00e9m \u00e9 utilizada para definir configura\u00e7\u00f5es e par\u00e2metros de inicializa\u00e7\u00e3o dos servi\u00e7os. O Shepherd j\u00e1 est\u00e1 em uso na distribui\u00e7\u00e3o GNU Guix System e tamb\u00e9m \u00e9 direcionado para uso no GNU\/Hurd, mas pode operar em qualquer sistema operacional compat\u00edvel com POSIX para o qual a linguagem Guile esteja dispon\u00edvel.      <\/p>\n<p>O Shepherd realiza o trabalho de iniciar e parar servi\u00e7os, levando em considera\u00e7\u00e3o as inter-rela\u00e7\u00f5es entre os servi\u00e7os, definindo e iniciando dinamicamente servi\u00e7os dos quais um servi\u00e7o selecionado depende. O Shepherd tamb\u00e9m suporta a defini\u00e7\u00e3o de conflitos entre servi\u00e7os e evita sua execu\u00e7\u00e3o simult\u00e2nea. O projeto pode ser utilizado tanto como o sistema de inicializa\u00e7\u00e3o principal (init com PID 1) quanto de forma isolada para gerenciar processos em segundo plano de usu\u00e1rios individuais (por exemplo, para iniciar tor, privoxy, mcron, etc.) com execu\u00e7\u00e3o sob os direitos desses usu\u00e1rios.     <\/p>\n<p>As principais novidades do GNU Shepherd 1.0.0:  <\/p>\n<ul>\n<li class=\"l\"> Adicionada a suporte a servi\u00e7os que executam comandos ou c\u00f3digo em Scheme periodicamente conforme um cronograma especificado.\n<li class=\"l\"> O comando &#171;herd status SERVICE&#187; agora exibe informa\u00e7\u00f5es de alta n\u00edvel sobre os servi\u00e7os, como PID, comando e endere\u00e7os que recebem solicita\u00e7\u00f5es de rede, al\u00e9m de resumos das mensagens recentemente adicionadas ao log. Al\u00e9m disso, este comando agora mostra as a\u00e7\u00f5es do usu\u00e1rio aplic\u00e1veis ao servi\u00e7o e informa sobre a presen\u00e7a de um servi\u00e7o substituto que ser\u00e1 aplicado ap\u00f3s a reinicializa\u00e7\u00e3o do servi\u00e7o atual.\n<li class=\"l\"> O comando &#171;herd status root&#187; n\u00e3o \u00e9 mais um sin\u00f4nimo de &#171;herd status&#187; e exibe informa\u00e7\u00f5es sobre o processo root do shepherd.\n<li class=\"l\"> Uma nova possibilidade foi adicionada para a plataforma Linux, permitindo reinicializa\u00e7\u00e3o usando o mecanismo kexec (&#171;reboot &#8212;kexec&#187;) para substituir o n\u00facleo do Linux sem uma reinicializa\u00e7\u00e3o f\u00edsica.\n<li class=\"l\"> Adicionado o servi\u00e7o de rota\u00e7\u00e3o de logs, respons\u00e1vel pela rota\u00e7\u00e3o peri\u00f3dica dos logs e pela remo\u00e7\u00e3o de logs obsoletos.\n<li class=\"l\"> Adicionado o servi\u00e7o system-log, que pode ser utilizado como uma substitui\u00e7\u00e3o para o tradicional sistema syslogd.\n<li class=\"l\"> Foi adicionado o servi\u00e7o timer para agendar comandos em um hor\u00e1rio espec\u00edfico, semelhante \u00e0 ferramenta &#171;at&#187;. Por exemplo, &#171;herd schedule timer at 07:00 &#8212; mpg123 alarm.mp3&#187;.\n<li class=\"l\"> Foi introduzido o servi\u00e7o transient para executar comandos em segundo plano, semelhante \u00e0 ferramenta systemd-run.
