Often, for work reasons, I have to create xubuntu virtual machines that I use for embedded development.
How can I (starting from an iso image and a blank VM) avoid installing things I don't need, such as libreoffice? On google I found no way to do a manual or custom installation.
Edit: I don't want and don't need to customize a Live CD ISO. I need a custom installation cd that installs on my hard disk the packages I decide.
I tried cubic, and he created a live cd for me, but not an installation cd.
