I think the pb is that it's so barebone that pretty much nothing works out of the box. One has to add a few more components, depending on which application needs to run (as an OS alone is, well, not an end in itself). However, that's where it stings : adding "components", yet but which ones ? in which order ? how ? Componentization was not a topic, so there's no tool, almost no doc, just tribal knowledge on the topic. That makes it essentially useless for the vast majority of humanity.

That does make sense. I suppose one could gather a record by hooking the kernel to log which files were accessed and which were not. But that would be a lot of trouble and the end result would just kill the cacheability of the base OS layer of those emulation images.
