The answer, I think, depends a little bit on exactly why
you are asking ... 

It is best to think of the Ganymede site as "a discovery
site" ... a place to get new things and all the pre-reqs it requires.
Not a place to get updates from. 

While it is true there will eventually be maintenance
updates put on the Ganymede update site, those maintenance updates only
come from the projects update sites ... in other words, nothing new, and
nothing not already available via updates from elsewhere. The only reason
we put maintenance updates there at all is that in case someone installs
something "fresh" from there, after the coordinated maintenance
then they get all the fixes during the first install, instead of having
to install once, and then get updates to things already installed. 

If you are really asking if you can use the Ganymede update
site as an update site for some product or unrelated project instead of
using an individual project site, then the answer is "no". That
would be ill advised for several reasons: most important, if there was
an important bug fix that a project makes off cycle, then users can only
get that from the projects update site ... they can not get it from Ganymede
until the coordinated release. Next important, Ganymede is pretty big,
so might have performance implications (during update browsing/search).


Another sort-of complication (in the sense of improved
feature :) is that P2, as I understand it, doesn't care where it gets updates
from ... that is, to pick an example that would never happen, if it "sees"
there is an update to JDT on the WTP site ... then it will get it (it doesn't
really care where it came from originally). In otherwords, it is hard to
_limit_ updates to only come from the Ganymede site, just in case that's
related to why you were asking. [And, I admit ... not sure about how P2
works ... I'm sure we'll be learning]. 

So .. hope that helps ... if this doesn't get at the heart
of your question, perhaps you could ask again explaining what you are trying
to accomplish.

As far as I know, all EPP packages are
assembled from Ganymede bits (modeling is, certainly).  So, the Ganymede
update site should serve as a package update site, and it’s already listed
as an available site.

Best,
Rich

Hi there! 

I had a question come up today about EPP and was wondering if you guys
could help. I'm sure it's a n00b question, but I'm going to ask anyway.

So let's say I download JEE. And I want to update it as a whole, not as
individual projects. Is there a concept of a "package" update
site as opposed to the individual project or release update sites? 

Thanks in advance
