Ok, though one thing that's going to be important to me at least is the
ability to mutate the user list "offline" - the use case here is
something like an installer where you're operating on a different
target root. So in addition to the DBus API, there would need to be a
way to use a shared library API with a "const char *chroot" type
argument (as e.g. ostree_sysroot_new() has now).
Ideally that ends up being dumb filesystem manipulation, maybe
invalidating some database-type caches that are then regenerated on
boot or so. And I should be able to control whether or not fdatasync()
occurs on written files. A bit more on the fdatasync() topic here:
