In fact, it means to install using the package files in some local directory,
i.e., "assume the packages are already downloaded".

It would be reasonable to copy over downloaded packages.

I believe there are commands / techniques that would then make it fairly
easy to install that specific set of packages "from scratch" (but from
the local copy of the packages).  Copying *installed* file hierarchies
is trickier because of permission / ownership concerns.
