4. Localboot products: automatic software distribution with <strong>opsi</strong><br />
Sometimes a setup program wants to perform a reboot after installation. You will have<br />
to decide case by case whether to do so or not. Microsoft makes no explicit statement<br />
how to handle this. When the setup is done, 'disco32.exe' can be started again to take<br />
the second snapshot and analyze the differences between the two snapshots. Then it<br />
creates a MSI package for software distribution. This package contains everything to<br />
reproduce the installation.<br />
4.3.1.6.2. Orca<br />
Microsoft outlines the functions of the program “Orca” as follows:<br />
Because of the restrictions of existing tools for the Windows Installer, it might be<br />
necessary to edit the MSI packages. To perform this task, Orca is provided by the<br />
Windows Installer SDK.<br />
In principle with Orca you can do a lot of jobs concerning MSI packages, but for more<br />
complex tasks it is too difficult to handle. So Ocra is suitable mainly for performing some<br />
small patches and customization.<br />
Anyway Orca is a great tool to discover the internal structure of MSI packages and to<br />
understand the basic principles of a setup information database.<br />
After opening a MSI package with Orca a list of tables will be shown that look like<br />
database tables. And that is what they basically are.<br />
When you click on the table named “Files” it will look like this:<br />
On the right side there is a list of all files required for installation. Each file has got an<br />
unique key for identification, which is shown in the first column.<br />
