Duplicating an Ubuntu machine so you can install Rivendell

(Or a Debian Machine)

First you need to create a list of installed packages

sudo dpkg --get-selections > installed-software.txt

And if you wanted to use the list to reinstall this software on a fresh ubuntu setup,

sudo dpkg --set-selections < installed-software.txt

followed by

sudo dselect

In dselect choose the option install this will install everything from your text file

If dselect isn't installed you might have to install it by typing

sudo apt-get install dselect

[edit]

Hints

To save installation time copy the entire group of previously downloaded deb packages from the /var/cache/apt/archives/

This will save downloading everything again.

Also you want to copy the /etc/apt/sources.list

Don't forget to enter the repository key from Alban's website. (If using Alban's packages)
