I think the use cases are rather obvious. I build a device and I like
to rearrange existing models into a beautiful hierarchy (for some
definition of beauty).
This would be pretty complicated. Suppose I define my own beautiful
structure like this:
container my-interfaces {
x:mount-point "if" {
x:mount-module "ietf-interfaces";
}
}
container my-routing {
x:mount-point "rtr" {
x:mount-module "ietf-routing";
}
}
Note that with the mount-point defined in my draft, each mount-point
becomes itw own "jailed" or "chrooted" tree. So references cannot
cross mount points.
Could be the same here.
In this case, we have references between ietf-routing and
ietf-interfaces. How would they work?
How do they work in your solution? If interfaces is jailed and routing
is jailed, how does routing refer to the interfaces?
My solution does not support "name module mount". It only supports
mouting of a "complete" set of modules (that are chrooted) - simply
because this is what we understand, have implemented, and have been
running for the last ~5 years. (The same goes for ODL, I believe).
OK. I understand now that the whole set of modules on a mount point
form one chroot environment. This was not clear to me yet but of
course makes a lot of sense. So a static schema mount would have to
define a set of modules and not just a single module to lead to the
same chrooted behavior.
Yes, but then you can't use it to define your own beautiful
structure.
I am not sure yet why this is the case.
Each such mount point is chrooted. This implies that if you want to
put module A in some place, and B has a reference to A, A and B must
be mounted together. Thus I cannot put them anywhere to form a
beautiful hierarchy.
As long as B is mounted in the same datastore as A then is it possible
that B could moved to be mounted on some other path?
References to/from B would need to be fixed up, or are you saying that
fixing the references is intractable?
