Second generation build algorithms are centered around *not*

obtain this
info on an as-needed basis instead of an O(n) scan.
Does this require some kind of daemon running in the background?
Yes, but... practically nobody uses the daemon (which is
optional).
There's practically no difference in performance against a simple
scan of the FS.
