And just for completeness:
	zypper with *.solv files avoids many of the problems with "caching" seen in yum/apt/smart,
	but introduces some other problems (binary format maintenance is really painfully hard,
	and similarly merging hash buckets and memorization are overly complex, but these are different
	issues mentioned solely in passing).
