-      a. (If the dependencies are not met, then no part of far f will be installed. It is not legal to partially install a far into the workspace.)

+      a.  It is supported to "partially" install a far. A partial installation of a far means that 1 or more packages and/or platforms are installed into the workspace from the far. For each package or platform p in f, p's dependencies must be satisfied by a package in the workspace.

+      a.  It is supported to "partially" remove a far. In this case, one or more of the packages or platforms in the far can be removed, provided that for each package and platform p in the workspace w, there does not exist a module m such that m depends on p.

       6.  When installing a far f into workspace w, for each package p in f, allow the user to install in p's default location, or choose a new location l (which must be unoccupied) within the workspace. Record this location l in the database. Each package p in f will be recorded in the database, associated with the GUID of f, as well as the actual install location l. (So we will know which far each package belongs to.)

-      7.  When installing a far f into workspace w, if there exists a package p in w, and p is in f, then the user must be prompted to choose a location that does not collide with the location of p in workspace w. We will end up with two instances of p in w at two distinct locations.

       8.  A far f may replace a far g in the workspace w, iff for each module m contained in w, if m depends on a package p, and p is only contained in g, then there must exist a package q in f, such that m depends on q. The net effect is that g is removed and f is installed, in one operation. The normal rules for installing f still apply--the dependencies of the modules of f must be satisfied. After the replacement, it must be the case that all the modules dependencies in the workspace are satisfied. Note that it is possible to backrev a package in this way.
