[Cialug] Moving Linux from one disk to another

[Nathan C. Smith]

What are some good ways to move linux from one disk to another?  I have a running installation on a 20 GB disk I'd like to move to something a little bigger and then take advantage of the new space.  Is that something I could do with DD and then use another program to expand my filesystems into the available space?  What would I use to expand the filesystem and is it available from the command line or by using knoppix, etc.?

Is there anything quick and easy?  I may give ghost a try but I thought I would ask the question.

Looking for tips pointers and valuable life experience.  TIA.
