Eu tenho o servidor Ubuntu 10.10 remoto rodando no sistema raid. Eu fiz o upgrade do pacote ontem à noite por razões de segurança. Durante a atualização, a tela de instalação do grub apareceu e me perguntou qual partição eu queria instalar o grub. As opções são sda, sdb, md1 e md2. Eu decido instalá-los nas partições sda e sdb.
Eu me pergunto, eu tomei uma decisão verdadeira? Se a máquina for reinicializada, ela poderá ser inicializada com segurança?
