Hi,

Hrmpf. I should have advised you to use
-rm_r /home --
after the -mv command.
(And a -volid command to override the default Volume Id "ISOIMAGE".)

That's the minimum size of a CD session. The size needed for a new
superblock and directory tree was even smaller. (The Spring Snowflake
image data were not written again.)

Much more than 600 KiB were wasted by the hardware. 22 MiB gap between
the sessions.
You may still mount the older session:
mount -o sbsector=0 /dev/sr0 /your/mount/directory
and, after you added more sessions, the second one by
mount -o sbsector=128183 /dev/sr0 /your/mount/directory
(Linux mount understands -o session=2 with CD, but not with DVD.)

The next gap will be smaller, according to the predicted Next Writable
Address (drive's idea, not mine):
> Media nwa : 135385s
135385 - 128183 - 38 = 7164 = 14 MiB
So one should bundle changes in the same session. I.e. next time you
add more images, you may apply above -rm_r to get rid of the empty
directory chain.

Its announcement will be in the reply to the last GET CONFIGURATION
command in the output of
xorriso -scsi_log on -outdev /dev/sr0
when a (still) writable CD-R is inserted.
But there is no need to endanger more CD-Rs by Stream Recording.
I know already that there are dishonest drives around.
So just make always sure that the Xfburn feature is disabled and that
you do not enable it in xorriso runs.
If you can get your hands on a DVD-RAM, then it would become interesting
again. It's the only DVD medium where Stream Recording brings benefits.
But don't buy one. They are not worth the money.
The original reason why i implemented Stream Recording was to get full
2x speed out of BD-RE media. 9 MiB/s is slow enough for a medium with
23098 MiB of capacity. Other than its ancestor DVD-RAM, the BD-RE
media type is about the best re-usable one of all.
Have a nice day :)
