Very often, a list of so-called Frequently Asked Questions is simply an excuse not to write decent documentation. If you find problems with our documentation, please let us know and we will try to fix the documentation to meet your needs.

That said, there are some commonly asked questions that don't fit elsewhere, so we will answer them here.

  1. Why should I use the VDT instead of getting software directly from the people that make it?
    1. Much of the software provided by the VDT is complex to install and configure. The VDT installation process hopefully makes this much easier for you.
    2. We patch some of the software with the latest bug fixes that are hard to track down and apply yourself.
    3. We provide a complete package so you don't have to get software from many locations

  2. How do I download the VDT?
    Normally you don't, but you use Pacman--an installation program--to do so. If you wish you can download RPMs and Debian packages for a subset of the VDT.

  3. Why do you use Pacman instead of RPM, Debian packages, or <Your favorite packaging format>?
    Pacman can run as root or non-root. Pacman is easy for non-system adminstrators to use. Pacman is a convenient solution when software packages are delivered to us in many formats. And we are planning on supplying a more complete set of RPMs and Debian packages in the future so you can choose what you prefer.
