I don't doubt you will come up with a workable solution at build time. However, working out a valid graph at execution time is trivial and efficient, given a list of precedence relations of the kind you're suggesting. In fact you don't even have to work out the graph before starting the initialization, it's also trivial to keep a count of unsatisfied initialization conditions at the beginning of each initialization sequence and block until the count goes to zero. (In essence, evaluate a priority sort on the fly.)
