Is there any technique out there (I've seen vague references to "cluster manager") that will allow me to do the equivalent of installing fedora in user mode to a disk image file? In other words, I want to be able to do the install without taking down the system, but instead simply install to a filesystem image on disk or an actual physical disk drive. Then I could pop the drive in another box, or boot it as a VM, etc. I'm not actually needing this for anything, I'm just curious if this sort of thing has been done, and if so, what I should be reading to find out more :-).
