Last time I added a DVD burner to my Build system, it cost $29 (USD) and
this was for a very good, reliable unit.  Not worth my time and immense
hassle to do otherwise ....

What about:

What isn't clear?? As "need to" means **MUST**.... <hmmmm>.
Why did you even make an attempt without the createrepro command??
Two to three minutes of your time wasn't worth it (but taking our time
is, of course) :-):-) ...

While I believe your bug reports, I install CentOS on RAID + LVM
everyday without any problems, private kernel patches, etc. -- as a
counter-example.

Now, let's see if we understand the situation clearly:

   1.  This is a "one-time" conversion (will "throw the CD away when done") ...

   2.  You're migrating a system from Ubuntu to CentOS (e.g., a different
        version / patch level of LVM + RAID) and *hope* to keep data
        consistency and reliability ...

   3.  You have a backup of this precious data, yes / no??  If no, eegaddss....

   4.  So, why not just do a wipe + fresh install and reload the data???

Now how much time have you spent on this "project" so far??  I believe
the above would be done 2 to 3x times over by now ....

Plus, you've found out that it is a lot more than "just a mkisofs command
with a few arguments" (and that you have to follow instructions precisely
or things just don't WORK(tm)).

Hmmmm....
