We need unioning to keep the image creation consistent with CDs and to
severely reduce the download size (remember that squashfs reduces the
size considerably). What you are proposing is a normal installed system
on a USB disk, we wouldn't need archiso to create that, but much leaner
scripts that only create the root and copy it to a new filesystem.
Also, I'd like to have a USB image creator in the future, which takes an
existing USB device (potentially with files on it) and installs the live
system on it. It is much more convenient to just have 3 squashfs files
here instead of a whole operating system.
The beauty of this approach is that you can simply delete the
/livesystem folder from the USB stick and have the image in its original
We could still offer an option in archiso to just create a filesystem
from the workdir instead of squashing and unioning - it has its uses.
