Short summary, local copy and link to the originating site,
http://home.pages.de/~ohly/#mkisofs-root are posted on my page since a
while ago. Just search for word "Ohly."

It's mkisofs patch. It's not included into official distribution of
mkisofs, because we failed to reach consensus with maintainer that it's
a worthy extention [which we, Patrick and me, believe it is and I do
recommend it].

Yes. But once you give up the compression, tar is easy to trade for
opportunity of streaming data directly to media and "seamless"
multi-sessioning.

Well, you naturally won't be able to reach same media utilization as
with compression, but overhead is hardly different from what you would
have on any other file system. A.
