A while ago I looked at the ext3cow file system. I am interested in getting it running under lucid. I was wondering whether anyone had successfully set it up on their system and could offer any tips? I have had a quick google around but not found any mentions of getting it working under Ubuntu.

I too looked at ext3cow a while ago and spent some time in setting things up and testing.
What I found and what I suspect you will find, is that what you really require is distributed VCS such as bzr.
Having the file system history is very useful and ext3cow takes care of this for you automatically without the hassle of having to commit. But in reality having the option to commit, add log details, revert easily and graphically view the history makes the committing a small overhead to manage.
As there website says:
• It is totally modular, requiring no changes to kernel or VFS interfaces
It hasn't been in development for a couple of years. I am doubtful but hopeful give it a try.
Or maybe look at some alternatives.
