[Voyage-linux] log the stdout of a process started by start-stop-daemon

[Francisco José Sánchez]

Ok Toni,

I think that the problem is the moment executed script. Question ¿is
mounted /var/log?

For depuration include into script a mount command before touch file log.

PD: normaly, /var/log is mount tmpfs (/etc/init.d/mountkernfs). Is the
execution your script before or after mountkernfs?

Best regards.
