I have a system that we are running in production that there was an

we've tweaked that we would hate to just start over on it.
There's a tool for OSX called "Carbon Copy Cloner" that would take care
of this for me, which is basically a series of copy commands that takes
the filesystem from one drive to another, preserving EVERYTHING
important, and then bless the boot volume.
If you want two more identical drives then use dump, not tar, but you'd
have to have them sliced/partitioned up the same beforehand and it
wouldn't do bootblocks.
You would? Why? restore doesn't care where you're restoring to... you'd
just need to make sure you were in / before restoring and then tweak
/etc/fstab to suit...
I understood the question to be how to create two identical *disks* not two
identical directory trees. So unless the disks were partitioned and sliced
the same before you used dump/restore then you wouldn't end up with identical
disks. If all you want is two identical directory trees, then slicing and
partitioning are irrelevant.

Partitioning IS releveant in my situation, but they don't have to be
perfectly the same. We have a rather unique system setup on that box to
where /var is insanely huge compared to the average boxen. There are a
few other requirements, but being perfectly identical isn't one of them.
It needs to be running the same directory tree upon boot, and be basically
the same system.
