Dependency On Server At Boot

Please navigate the wiki via the Page List to the right.

Project Description

This project enables you to test whether a server is contactable during boot and execute a series of commands depending on the outcome. It is probably easiest to understand from an example.

The Problem

You have a laptop which when you are in the office needs to automatically mount some shares from an internal server. When travelling you don't want the laptop to attempt to automount the shares because that produces boot errors and boot delays. So a plain auto entry in /etc/fstab is out.

The Solution

Install this project. Enter the shares in /etc/fstab with the noauto option. Add the server to the /etc/dosab/server.list file. Add the mount commands to a file you create called /etc/dosab/server-name.available. (In this case if the server is unavailable you just want to do nothing so there is no server-name.unavailable file.

Now, every time you boot the laptop it will mount the shares if the server is available and otherwise do nothing.

Actual example files are available in the source tree in src/conf/etc and installed by the project in $docdir (often /usr/share/doc/server-dependency or /usr/local/share/doc/server-dependency).
