You need a few more things for a generic live, e.g. support for all
the disk controllers, support for aufs and other union filesystems,
the full USB stack, and several drivers from the scsi/ bundle, which
are needed to deal with cdroms...
Yes, you must include everything needed to read the cdrom. It's
true it includes the scsi bundle and the USB stack, but not the disk
controllers. And support for union filesystems only if they are needed
to mount the cdrom ( don't see why). My own trend would be to rebuild
the kernel with those drivers statically linked and boot directly to the
cdrom without and initramfs.
