There are tons of built-in assumptions regarding system state on this thread. I believe the argument being offered is that for the vast majority of desktop users, the default upstream approach of flatfiles serves the common use case fine. If you think the majority of desktop users are using more than one machine, or NIS+ or anything complicated, then we already disagree on the base case ;) > >> The time required to parse >> the average GNOME single user desktop machine (I've got 44 users and >> 69 groups on that box) is likely smaller than the overhead of a DB. > > No, since the DB can have frequent pages locked into memory.
