make sure you aren't overburning these things because a hell of a lot of cd/dvd
burners *DON'T* support this, and the snap 3 386 live cd iso are overburned [703 megs
instead of the standard 650/702 megs].

It's easy to look at the size of the image and the capacity of the CD and decide
if it will fit. I have 720 and 730 CDs from an obscure source called Office Max.
You can often get them from newegg as well, I never ordered anything special,
they just came that way.
You may have to use the overburn option to cdrecord, I don't ever recall doing
that, but it's there. I use the cdrecord from the author rather than the hack
one which comes with Fedora and some other distributions, that might be a factor.
In short, I burn these on a variety of burners, CD and DVD, and have no problem
with the size. You might have some small media, in which case a quick investment
would be in order, but larger sizes are available.

You just don't get it, do you?
The *MEDIA* has *NOTHING* to do the problem.
The *PROBLEM* with *OVERBURNING* an ISO CD's that's *NOT FOR YOUR PERSONAL USE*
is that a lot of the *DRIVE HARDWARE* for CDRW/DVDRW BURNERS DO NOT SUPPORT OVERBURNING AT
ALL.
THE HARDWARE SUPPORT FOR IT DOES NOT EXIST IN THE DRIVE AT ALL ANYMORE. I KNOW BOTH OF MY
LITEON CD/DVD BURNERS DON'T SUPPORT IT. I'M TAKING ABOUT DVD BURNERS THAT CAN READ
AND WRITE DVD-RAM HERE.
OVERBURNING OUSTSIDE OF A FEW ODDBALL DRIVES WAS NEVER VERY COMMON FOR A NUMBER OF
REASONS, WHICH HAD TO DO WITH THE LIMITS OF THE 650 MEG CD'S, WHICH WERE PRETTY MUCH
THE ONLY CD MEDIA THERE WAS A NEED TO USE OVERBURNING TO BEGIN WITH.
WHEN THE 702 MEG CD'S BECAME THE STANDARD, OVERBURNING FADED AWAY FROM THE DRIVE
MECHS FOR A GOOD REASON. THE DISKS CREATED USING IT WERE UNSTABLE. ODDS WERE GOOD THAT THE
PRETTY MUCH ONLY DRIVE THAT COULD READ AN OVERBURNED CD WAS THE ONE THAT CREATED IT.
SO USING AN OVERBURNED CD FOR AN ISO DISTRBUTION BASE IS A VERY,VERY BAD IDEA TO BEGIN
WITH,SINCE IT'S GOING TO DO NOTHING BUT CREATE UNNECESSARY PROBLEMS IN THE END.
