// With the forward rollback boundaries assigned, we can now go

// rollback boundaries. Backward rollback boundaries are used when
// the chain is going "backwards" which (AFAIK) only happens during
// uninstall.
//
// Consider the scenario with three packages: A, B and C. Packages A
// and C are marked as rollback boundary packages and package B is
// not. The naive implementation would execute the chain like this
// (numbers indicate where rollback boundaries would end up):
// install: 1 A B 2 C
// uninstall: 2 C B 1 A
//
// The uninstall chain is wrong, A and B should be grouped together
// not C and B. The fix is to label packages with a "backwards"
// rollback boundary used during uninstall. The backwards rollback
// boundaries are assigned to the package *before* the next rollback
// boundary. Using our example from above again, I'll mark the
// backwards rollback boundaries prime (aka: with ').
// install: 1 A B 1' 2 C 2'
// uninstall: 2' C 2 1' B A 1
//
// If the marked boundaries are ignored during install you get the
// same thing as above (good) and if the non-marked boundaries are
// ignored during uninstall then A and B are correctly grouped.
// Here's what it looks like without all the markers:
// install: 1 A B 2 C
// uninstall: 2 C 1 B A
// Woot!
