Sup\u00f5e-se que, em compara\u00e7\u00e3o com uma reinicializa\u00e7\u00e3o normal, a reinicializa\u00e7\u00e3o suave reduzir\u00e1 o tempo de inatividade durante a atualiza\u00e7\u00e3o de ambientes que utilizam imagens de sistema prontas.       <\/p>\n<p>O novo modo permitir\u00e1 encerrar todos os processos no espa\u00e7o do usu\u00e1rio, ap\u00f3s o que o sistema de arquivos raiz ser\u00e1 substitu\u00eddo pela nova vers\u00e3o e o processo de inicializa\u00e7\u00e3o do sistema ser\u00e1 iniciado, sem reiniciar o n\u00facleo.

Assim, ser\u00e1 poss\u00edvel reduzir significativamente o tempo de substitui\u00e7\u00e3o de uma vers\u00e3o do sistema por outra e garantir a transfer\u00eancia sem interrup\u00e7\u00f5es de recursos para os servi\u00e7os mais importantes, que continuar\u00e3o a funcionar sem parar.    <\/p>\n<p>A acelera\u00e7\u00e3o do rein\u00edcio \u00e9 alcan\u00e7ada pela exclus\u00e3o de etapas relativamente longas, como a inicializa\u00e7\u00e3o de hardware, opera\u00e7\u00e3o do carregador, inicializa\u00e7\u00e3o do n\u00facleo, inicializa\u00e7\u00e3o de drivers, carregamento de firmwares e processamento de initrd. Para atualizar o n\u00facleo em conjunto com a reinicializa\u00e7\u00e3o suave, prop\u00f5e-se usar o mecanismo livepatch para aplicar corre\u00e7\u00f5es no n\u00facleo Linux em funcionamento sem uma
