It uses growisofs to burn writable DVD,
but the same method also works with cdrecord + writable CD.

O_DIRECT might be sufficient, but it turned out that this
alone is not sufficient: the buffers used by the programs
must have a certain alignment. This is not guaranteed
without modifying the way how those programs allocate

It does: 1 second = 75 blocks = 2048 bytes/block * 75 blocks = 150KB

g was not done properly by mkisofs
(as far as I remember, it padded to a multiple of 16 blocks and even
that was disabled by default), but on Feb 15 2003 padding by
exactly the required 150 blocks was added (according to mkisofs'
changelog).

This patch adds two new command line options:

but why should I? Isn't that the task of the original porter?
I have no need for cdrtools on the Amiga and I have
no time for it. And no, it is not because I still earn some money by
selling my own shareware CD writing software on the Amiga - the money
really is insignificant now
- without some kind of patch gruft deleted before my latest
backup is restored when copying back the latest session
So I'll continue to use my modified mkisofs, but I won't argue
for its inclusion in mainline mkisofs unless other users also
find it useful.

Ah, good to kno

The solution for both might be a more elaborate reusal of
the old directory structure, where new entries overwrite
the old ones.
Questions:
Is there a need for this patch?
Joerg and James, are you willing to include it in the official
release of mkisofs? What would you like to see modified
er one or more
TEST_UNIT_READY can be used normally again, without relying on SCSI

I never said that. I only wanted to get the clarification that nothing
like that was implied implicit

might do that in the future? If it's the latter, what makes you think
so?

ignored this sentence and in practice test writes work very well even

However, the currently available version is limited to backing up one

add (
#ifdef ADD_1_2

which really only work when #ifdef is evaluated before the macro. Is
there really any rule in a C standard that makes the AIX and GNU C
behavior noncompliant?
