Well now that you ask,
I would make an image of your up and running system. I do that anyway for a surefire backup, but if you want to clone this system to another box, it is very easy to grab that image and install it to the new box.
Partimage works very nicely for this as it only copies the used areas of the disk as apposed to dd which copies everything ( used or not ). In other words partimage is much faster.
Also, I copy the partition table with sfdisk
which makes it very handy to copy that file onto another hard drive.
