Here is a link to a blog post describing the steps I took to lock down ubuntu to use as public access machines.  We have had them running for well over a year with no problems.  The scripts at the end of the article are run at boot time and restore any changes that may have been made to the desktop etc.

This was done with an earlier version of ubuntu, but I recently tried it with 9.04 and it worked fine.

you have any ideas.

"I have been experimenting with Ubuntu with the intention of
installing it on our public computers.  One roadblock is that we use
Faronics Deep Freeze.  We are very pleased with it but they don’t
support Ubuntu and have no plans to do so.  Do you know of an open
source alternative to Deep Freeze?"

She sent this after attending my open source workshop where I listed a
series of open source apps she could use in her library.

Thanks in advance for any pointers,
