I just went through this on FC5. What I discovered was, you *can* burn
an image of 4.7GB or 8GB in size, but none of the files in that image
can exceed 2GB in size (this seems to be a mkisofs limitation).
...
It's as much a limitation of the ISO9660 format, where the maximum size of
a file fragment is 2 GB. Some OSs handle fragmented files on ISOs, some do
not.
So,
what I did was to break up the large files into smaller chunks. (Its
just as easy to cat them back together and pipe that output to a tar
command.) If you look at DVD movies, you'll see that each VOB file is
around 1GB in size (max), so they don't have that problem anyways.
I don't think there is another solution for for large files, yet.
There is, if compatibility is not an issue.
Actually, what I do is dump or tar directly to a DVD. I set the "tape
size" in each program to the size of a DVD, as blocks in the appropriate
blocksize. So I'm making DVDs with no filesystem. I believe that this is
/more/ future-proof, as, in the future, rather than getting a working
then-old-style filesystem working and a then-old-style restore or tar
working, I only have to do the latter. I write the DVDs with "growisofs
-dvd-compat -Z /dev/dvd=/tmp/dvd".
