I would like to perform the following remaster:

1. I want all the base system files and drivers available in knoppix (wireless, display, audio, bluetooth etc).
2. I would like to remove ALL packages except Virtualbox and its dependencies and a suitable file manager (maybe PCMANFM)
3. I would like to have only LXDE as a window manager (and its dependencies) and remove all the others, making LXDE the default.

I do not want any other software such as browser, email clients etc. My aim is to have a bootable hybrid iso from which I can launch VirtualBox and test various other systems virtually.

I was trying to get a list of installed packages using dpkg however I am not sure which ones should I leave to reach my goal.

Maybe someone can help me with this?

Thanks in advance.
