I don't know about you but when I have a directory, which is to be made into a LiveCD I just use mkisofs with the isolinux.bin
using:
/usr/bin/mkisofs -quiet -R -pad -V <volume ID> -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat -p myname -x lost+found -no-emul-boot -boot-load-size 4 -boot-info-table -o isoimage dir
The isolinux.bin and boot.cat need to be changed to specify your location of these files if syslinux is installed.
Using a SSD card though all you would need to do to create one is grub-install /dev/yourdevice
If you are only making an image I am not sure if livecd-iso-to-disk handles that but it is simple..
with a program c-section I use it just creates two loopback files and uses kpartx to map them, then I grub install to the mapper device and close the filehandle.
This will create a LiveUSB image you can put on any USB flash or SSD card I assume if you preload the SSD controller card modules.
Not sure how SSD works exactly, it is flash basically, just might not use USB protocol.
i would like to modify a live cd to have a root and user account and to mount a home directory for the user. i have taken a fedora 12 iso, broken it apart, made my changes and need to create the bootable iso image.
