Remastering Ubuntu's live disk

Many times I've used Ubuntu's livecd to test out an ailing system, but more than once I've wanted to add a utility, yes you can apt-get install from the live cd, but that assumes the system has a working internet connection, it's sometimes better to just build the cd yourself with the tools YOU want. Using the tips in this forum thread and this page, with help from this google search, I remastered my own custom version of ubuntu (with smartmontools among other things.) I consider the ability to make your own custom tools priceless when it comes to tech support.

Here's a twist - make a cd from your ubuntu install with remastersys.
