Right. There are tools for doing just that, from simply doing a dd of the hard 
drive (not really recomended) to tools like Clonezilla.  Basically, there 
isn't really a need to create a custom install disk, when simply "cloning" the 
installed system will work.

And even that is not a hard rule either.

Again that depends...

I "cloned" an "install" of Raspbian from one Pi to another.  (Actually the 
usual way to "install" Raspbian on a Pi is really a system clone, since I have 
not even seen a Raspbian installer -- one downloads a "disk image" which is 
simply dd'ed onto a micro sd card.

If the new machine uses an *identical* make/model (or at least *size*) disk as
the original, then you can just install the new machine's disk as a second
drive on the original machine and just dd the whole thing: 
"dd if=/dev/sda of=/dev/sdb".  This would take care of partitioning, GRUB, 
etc.
