For some time we have been using a modified version of @j.maus excellent ThinRoot system on our thin clients. Due to some work on another project I got the idea of trying a completely different approach for creating a Linux client image – Docker to the rescue!
For the last few days all of our thin clients have been booting a regular ubuntu system, and it works very well. Today, there was this announcement from Ubuntu about a kernel security update. All I had todo was
make ubuntu and 10 minutes later, the clients could be rebooted into a freshly built Ubuntu system with all the latest security updates integrated.
If you are interested, have a look at the GitHub repo: GitHub - oposs/dbrrg: Docker based RamRoot Generator
