Problem with iso9660-maven-plugin

Hi all,

I am trying to switch one of our 'projects' to Maven and am running into
some problems.

The project consists of some shell-scripts (which I want to replace with
Maven) and configurations to build an Ubuntu pre-seed Image. What the
scripts do in short:
- Mount an Ubuntu image
- Copy its content to a directory to work in
- Add our configurations
- Create a new Image

I have found a plugin to extract the image without mounting it (getting
rid of the need for 'sudo' in our script) and copying the configurations
is peanuts any day.
To repackage the image, I looked into the iso9660-maven-plugin, which
was said to do just that.

Now, when I run my project, it always stops with the following error:

[ERROR] Failed to execute goal

Looking through the code, it seems the plugin thinks the filename is too
long. I added some logging and built a SNAPSHOT version to play with,
but I am not quite sure about the calculation of the filename-length.
All names that go in are exactly 64 characters long, but the plugin
wants to shorten them still.

I was hoping that Mr. Connolly could perhaps take another look at it and
give me some pointer/update the current version to work correctly.

A simple test-case is to just unpack an Ubuntu image (I was testing with
10.04.4 amd64) and try to repackage it.

Thanks.
