Files are saved using a full path in the rollback directory, which makes the installation non-relocatable on Linux. Is it possible to specify a rollback rule saving relative-to-installation-directory path?

It was implemented using the full path to allow backing up any file in the system. If a relative path to the installdir is used, just files overwritten inside the installation directory will be easily reproduced in the backup but it would be hard to determine the destination of a file in the home directory.

In any case, I see your point. We will add your suggestion to our bug tracking system.

As a workaround, what you could do is move the contents of the backup to another directory, relative to the installation directory:

So, in pre-uninstall stage I will have to detect the current installation root directory and restore the rollback contents where the installation expects them?

If you want to restore the backup after uninstalling, you could use the <postUninstallationActionList>. You can get the current installation directory (in case you want to take into account manually moving the application) using the built-in variable ${installer_directory}.

I guess this can be implemented, but I hope you'll add an option to store relative-to-installation paths for files inside the install tree. This is especially useful on Linux for auto-mounted paths. I'm currently investigating other issues related to this and I'll post more messages later.

It is not currently possible to configure the prefix. The rollback directory uses the full path to the files to allow restoring modified files at any location in the system. If you are just interested in backing up the contents of the installation directory (or a subdirectory), you could manually create the backup using:

I would be interested in the automatic rollback facilities provided by InstallBuilder. I wonder why this was implemented using a full path?

It it going to create problems when installing to auto-mounted paths. The paths are expanded and there's an ugly /.automount/server/volume/path type of prefix in the rollback directory.
