In theory this should be super easy on most Linux systems because of the software repos.

On Debian based systems, on your existing development machine, you can do:

    dpkg --get-selections > installed_stuff.txt

Then copy the file "installed_stuff.txt" to the new machine/VM and do:

    dpkg --set-selections < installed_stuff.txt

It becomes a little more difficult when there are dependencies that aren't in the package system.

Another thing I've found useful is to have a git repo with my config files. Then on a new machine I can clone the repo and have access to all of them. I've been meaning to write a script that copies everything to the right location, but haven't got around to it yet.
