The idea is to identify installed packages by a hash of the information needed to build them. This hash is the new InstalledPackageId. The new installation directory for each instance is $libdir/$pkgid/$installedpackageid. The hash is computed during installation in installLib as well as during registration in generateRegistrationInfo.
Information used to compute the hash
The ABI hash becomes a field of InstalledPackageInfo. (What is it needed for?) For inplace package registration any packages with the same location must be unregistered.
Executables? Haddock? Garbage Collection? Installation Planner?
