Hi Folks,
Is there a pointer to any background reading material on this feature?
Here's the first paragraph of the design document, it's the closest
thing to an overview we have.
Linked images, and zones in particular, must keep certain packages in
sync with the global zone in order to be functional. The global zone
will constrain packages within the non-global zones and configure
special publishers in the non-global zone (NGZ). These publishers
(henceforth called system publishers) are special because the non-global
zone cannot make certain kinds of modifications to them. Among the
forbidden operations for the non-global zone on the system publishers
are deleting, disabling, removing or replacing origins provided by the
system repository, and any other operations which might prevent the
solver from meeting the constraints imposed by the constraint package.
The global zone must provide the means for the non-global zone to
configure itself with system publishers by providing information like
origins. The global zone also has to provide a connection to the system
publishers' repositories which is available even in a scratch zone. This
connection, broadly, is called the system repository.
If you're interested in a more detailed (slightly out of date) design
document, you can find it here:

Hi there,
If anyone's interested in following along with the system publisher work
that Brock and myself are doing, we've got a hg repository at:
ssh://[email protected]/hg/pkg/sysrepo-gate
Thanks Danek for setting that up.
This is a work-in-progress project-gate, and as such has not been
code-reviewed or tested in depth. It may not work, may damage your
machine and may insult your neighbours (enough disclaimers?)
The sysrepo work in general is captured by the following bugs:
https://defect.opensolaris.org/bz/buglist.cgi?&status_whiteboard=sysrepo
At the time of writing, there's just the basics of the server-side code
in the gate. Having built the gate, here's how to try it:
% pkg install pkg/sysrepo
% svcadm enable system/pkg/sysrepo
This should give you an apache instance running on port 15000.
That instance is automatically configured to provide services as a http
proxy, proxying local requests to all configured and enabled publishers
on your system (it can proxy http requests across to https://
repositories using the keys and certificates configured on your system)
It also provides direct http access to file:// repositories, so for
example, we can do:
timf@linn[204] pkg publisher pkg5-nightly
Publisher: pkg5-nightly

For normal http:// access to file:// repositories, you're still
better off
using the standard pkg.depotd server - performance is a little slower at
the moment using apache, and it doesn't provide all of the features that
the pkg.depotd does (notably, search is unavailable)
We don't have a notification alias for pushes to the
sysrepo-gate, but let me know if you're interested in getting
notification and I'll see what I can do.
cheers,
tim
