I'd say go for the former, but that's more a personal preference. We
probably want to look at what attributes we should have other than
these. PER_USER and READONLY comes to mind. 

By default we should probably go with exactly CALLOUT, PERSISTENCE,
READONLY. And we should probably hardcode things such that any property
whose keyname starts with 'user.' is always PER_USER, !READONLY and
!CALLOUT. Per-user probably requires a bit rework on hald_dbus.c.

One comment on this patch

This should probably be PACKAGE_LOCALSTATE_DIR so it works with
installing in /usr/local.

Many thanks,
David
