If you google on how to install Debian on the Pogoplug/Dockstar/Seagate Goflex Home/NET, you will ultimately wind up to the url: http://projects.doozan.com/debian/
However, the script is designed for newer kernels, and may not work (the script will fail and the logs will tell you that your "kernel is too old").
There are two ways of going about circumventing this problem:
1. Install Debian "Squeeze" and update to Wheezy:
Find your devices's IP address and connect via SSH:
Partition your flash drive with fdisk:
Download and run the Debian Squeeze installer:
Update to Wheezy:
And Voila! You're running Debian Wheezy!
2. Install Arch Linux or some other Linux derivative, boot from that, login and:
Install Rescue system (this replaces the Pogoplug partition with a powerful rescue system.
We also need to disable perl so the the debian-wheezy script does not bomb out. (after installing rescue)
then install Debian Wheezy as per original instructions.
This way is only recommended when you are already running a Linux distro other than the firmware pogoplug distribution. In my case, I have my dockstar running on ArchLinux, but I wanted to try the new Debian Wheezy on it. At first try, it bombed out complaining of "kernel too old" from the log files. But when I installed the Rescue Partition and installed wheezy again, it worked!
