After you've installed a particular distribution once, you 'can' the
pristine install either by tar'ing it up, or using LVM snapshots.
Depending on usage, you may need to do a little tailoring, such as
generating a unique ssh host key.

Another alternative is to use tools like 'debbootstrap' for doing an
install into another directory. For RH/FC the anaconda --rootpath
option may be useable to do the same thing, though I haven't tried it
myself.
