That's not equivalent to what installing a deb does. debs can have
"preinst" scripts which are executed *before* files are unpacked. I
guess that 99% of the preinst scripts just ensure clean upgrades,
which is not an issue for a live CD, but it should at least be kept in
mind that there is an at least theoretical potential for breakage
there.
