Ubuntu on Alix (aufs)

I did some further work on getting Ubuntu on the Alix. I have tested the basic kernel on my second Alix board (2c3). It works so far without problems.
In addition I did some research how to improve the installation. First I thought I would like to have the root file system read only. This manly to reduce the write access to the flash disc. For this I would have to create a ram disc and map several directories to this ram disc since some directories need to be writable. After some research and looking at the Voyage Linux distribution I found an other solution. On the next version of Voyage Linux they will use aufs. I did some tests with aufs and I think this could be the solution I use. I took the script from Voyage Linux and did some small changes to the script for mapping some directories for writing to a memfs. The script used by Voyage Linux is quite nice it will sync back the changes at shutdown and this way no log information get lost on normal shutdown.
I will post the change script later, since I need to do some changes until I think it fits all my needs.

    How has the testing gone? Id like to have a look at that script if possible…

    Oh I almost forgot about the script. It actually works quite well for me. I just would like to separate configuration from the executing script.

    I got know everything prepared but I have to check with the license of the script first. Since I could not find any license on the Voyage site I first have to ask about the license before releasing the code.

    […] I have put together a small description of how to use my syncro script and uploaded the script including the config file to the web server. I have mentioned this script before (Ubuntu on Alix (aufs)) […]
