Philip - the answer is relatively easy - as there are no patches in IPS. If
there will be a bug fix for SUNWxim it will be provided in form of a new
SUNWxim package (different timestamp or version) so you will just upgrade a
specific package. Even better - as not necessarily all files in a new
package will be different pkg will (it already does) fetch only files which
changed making an upgrade even quicker. Providing bug-fixes in form of a new
package version has been common on many other platforms like Linux and has
been working really well for them. The only main issue has been lack of
reliable rollback with such an approach except for installing old package
again which not always is the best option. In opensolaris thanks to BE you
can actually upgrade your system (or selected packages) on a new BE which is
a clone of current OS and reboot to it when you ready - if you want a 100%
(kind of) guarantee to rollback the change you reboot to old BE - I really
love it and I've been using it for some time now.

Ok Robert, Shawn, Dave and Bart.
I'm more or less convinced now.
Congrats to IPS)
rgds.
Although the basic concepts remind me of what conary can do, and could
do since 2004/05 ...
In fact conary does not only support tagged package versions and
rollbacks, but does support rollbacks on its own, rather than based on
ZFS. Also it finds on-disk changes of files under its control in less
than circa 4 secs. It governes files by their database id, not through
their full file names.
Is anybody interested in a detailed step by step feature comparison
conary vs. IPS?
Admittedly rPath's Wiki is not the most user-friendliest one. So I
could invest a few hours to write a summary myself.
Sure, why not. It is always good to know what's going on around us.
I would definitely like to read something like this.
But then from the practical point of view I think it is a way too late
for Sun to suddenly switch to something else like conary. So disputing
IPS vs conary to convince Sun to change their approach is just a waste
of time.
But then nothing stops you from creating a new project at open Solaris
(or not if you wish) and try to build a distribution based on conary.
Since you seem to infer that it is mature and feature-rich product you
should be able to get there relatively quickly, especially if you would
write some tool co conver ips manifests to conary manifests (or whatever
they are using). And then who knows, everything might happen :)
