 |
|
| How do I modify the startup script for a program in /etc/init.d such that it waits for dependent programs to start before attempting to start? Is there a timeout value? Will it autostart the dependent services? |

By way of example, from /etc/init.d/apache2
| Code: | depend() {
need net
use mysql dns logger netmount postgresql
after sshd
} |
The above snippet indicates: the service should not be started when net is not considered to be up; the service depends upon the optional mysql, dns, logger, netmount and postgresql services; and that the service should be started after the sshd service (if present) although no actual dependancy is present.
There is no timeout.
Dependancies will be started if they are otherwise present in the present runlevel. |

| So, if I am wanting to make sure that dansguardian starts after, but also depends upon squid and apache2 then should I use the keyword "need", "use" or "after"? |

| The 'need' flag indicates service dependence, the 'use' flag indicates logical dependence, the 'after' flag indicates ordering for user convenience. So, 'use'. |
