O script abaixo está funcionando bem na inicialização do sistema.
No entanto, suas mensagens de log não são mostradas em /var/log/boot.log , quando o sistema é inicializado.
Eu o comparei com outros scripts de init.d e não pude chegar a nenhuma conclusão sobre o que estou perdendo.
Quando eu o executo via linha de comando sudo service <script> start|stop|restart , as mensagens esperadas aparecem na saída do terminal.
O que devo fazer para obter as mensagens de log desse script em /var/log/boot.log sem canalizar sua saída para o arquivo de log, usando apenas /lib/lsb/init-functions ?
Estou no Ubuntu 14.04 LTS.
Abaixo está o script e a configuração do nível de execução.
O script (nome: rtorrent)
#!/bin/bash

Você (e eu) começou da suposição errada. De acordo com este ,
[...] the messages are printed the console and written to usplash (if applicable).
Há também este postar em SO dizendo que você deve preferir usar #!/bin/sh em vez de bash (mas não fornecer uma razão para isso).
Portanto, mesmo que não haja problema em usar bash , você não encontrará algo nos registros, apenas na tela.
