Package tar file into Linux bootable disc

First off let me say that I have very little experience with Linux.  

We use Finnix to image a lot of the machines we have here.  The old Finnix disc we currently use had dcfldd packaged into it so when we boot into Finnix we can use the full suite of dcfldd commands. The problem is no one remembers how that was done.

I downloaded the Finnix 104 .iso and the dcfldd .tar file today.  How do I incorporate dcfldd into the new Finnix bootable disc?

mount your .iso, copy all data to a new location on your disk, then add your new file, use a proper tool (mkisofs, genisoimage, ...) and create a new .iso
should work

I think this is what you are looking for: (Recreating Finnix).

Don't I need to add the dcfldd files to a certain location on the disc??

After you do this : from the list
chroot /finnix/build/source/FINNIX /bin/bash -l

You (are in the environment like after it booted off the cdrom )
And then the program needs to be found in /usr/bin ...
libraries in /usr/lib etc.

So the full path would then be:
/finnix/build/source/FINNIX/usr/bin
/finnix/build/source/FINNIX/usr/lib

etc.
