Any thoughts on my prior message?
Also, an important thing I have noticed is that when I do NOT have persistence installed
on a bootable USB drive (or when I have a bootable CD), the path to the boot media is
available as /mnt/live. However, when I include persistence on a bootable USB, there is
no path to the boot media, and the path /mnt/live exists but is empty. As I am counting
on pulling several files in from the boot media (but outside the squashfs file system)
into my local file system, it is important that there be consistency in where I might find
these files, whether or not persistence is installed on the boot media.
Can the /mnt/live path be enabled on a bootable USB with persistence installed?
Also, another possibility might be to include the external files I need in the actual
persistence overlay. Can I move files into this area? If so I will not need to do
surgery on the squashfs file system.
Thanks much for any help that can be offered.

Thanks much for the info, Jeremy. I ran the mkisofs script as you specified below (we are
on an i386 architecture) and re-burned a CD from the newly-created ISO file. On booting,
it gets to the point where it says "Booting the kernel.", hangs for a few
seconds, then the following appears on the screen:
--------------------------------------
WARNING: Cannot find root file system!
--------------------------------------
Create symlink /dev/root and then exit this shell to continue the boot sequence.
bash-3.2#
Any thoughts? Something obvious I am missing?
Thanks,
Todd

After creating a LiveCD ISO image, I'd like to be able to make
CDs
that are essentially identical, but have a small set of unique
per-user files. I have tried mounting the ISO, copying its contents
to a regular directory, making my changes on the Live CD file system
(not the internal squashfs file system) and recreating the ISO using
mkisofs. However, this new ISO (when burned to a CD) refuses to boot.
Is there a way I can modify the ISO image to include my per-user
files on
the
/mnt/live file system for each user (and have the resulting ISO be
bootable),
rather than running the whole livecd-creator process each time I want
a
new CD?
You'll have to run mkisofs with the appropriate options for making the
CD bootable on your arch. On x86, that's something like 'mkisofs -b
isolinux/isolinux.bin -c isolinux/isolinux.cat -no-emul-boot
-boot-info-table -boot-load-size 4 ....'
Alternately, you can also use the --base-on support to build derivative
images
