Maybe. But for most packages that I unpack this way to test, (1) the
package is already installed or I'm going to adopt it anyway, so I'll end
up installing it properly using setup, which will take care of other setup
like installed.db; and (2) the preremove and postinstall scripts either do
nothing or do only trivial things like updating config files.

So for most cases, it works just fine just to unpack the archive into the
root file system in order to test it.
