Lars, it's not entirely clear to me why you would subclass
folder_symlink from folder (although I guess I can see some
justification).
We should also think about the things which currently end up with
context_id null (which includes user, apm_*, acs_sc_* notification_*,
and portal_*). For the service ones they could be under the service
instance, but I think for users we should have another magic object to
hang users off (which would let us permission people to admin user
accounts via that magic object).
I would like there to be no null context_ids in acs_objects
(other than the security_context_root).
Also, you say
Today, in order to find the ID of the main site, you have to query
the site map for the site node with no parent, and the object_id will
be the main site. Having a deliberate magic object for the site root
should be slightly faster, and actually more robust, since we're
guaranteed to just have one.
but I think getting at it by using the url "/" will do it w/o a db
query at all (although I agree a magic object would be good to have as
well).
