a friend if mine and myself were building a small home server for the last months.
Said friend also wrote a python script to automatically download the install disc images from the FTP once a night.
This way, I have the actual versions at hand all the time and do not need to wait for a hour (or day-) long download when I find out I need a new image.
So I asked the dev of the script if he would like to open source the script and in return he said "sure but only if somebody also wants to have it, as I would need to tidy up the code before in this case".
So here you go, do you want to have the script? :)
