openSUSE-11.2: Evaluation

Partner organization:

With the 11.2 cycle, we want to offer users the ability to perform a
live system upgrade in the manner of Debian's dist-upgrade.
For the purpose of this cycle, we want to support dist-upgrade from the
previous version (11.1) only, as this is a sufficiently complicated
problem as is.
From the user's view, the difference is between being able to update
the system incrementally within the given version or service pack
running, to being ble to migrate with a system command ("zypper dup" or
similar) to a higher version altogether. In the Debian experience, the
set of base distributions is not necessarily limited, but it has been
Ubuntu's practice to define what starting points other than "release n-
1" are allowed (for instance, all LTS versions are purported to be able
to "apt dist-upgrade" to the top of the line, although I have heard of
problems trying to jump two years - 6.06->8.10 - in a fell swoop in
this manner :-). In the openSUSE scope, we should aim to be able to
"dup" between incremental versions, starting from 11.1 to 11.2, and
later 11.x to 12.0.

Business case (Partner benefit): With the introduction of the Zypper stack to SLE, we
finally reached the state of a featureful (which YOU was not) and fast,
reliable (which ZLM was not) update stack in the platform.
For enterprise use, some tweaks are still desirable (changelogs,
rollback, ...) which we are looking at, as well as improvements on the
Enterprise management front, which we are working on with our SRM
The only really significant competitive feature we are missing at this
point is the Debian/Ubuntu dist-upgrade functionality, which has a
powerful psychological impact at the Enterprise level and a much more
tangible impact at the small user / single user level: many with no IT
department do use Ubuntu these days on the basis that "chasing" Fedora
and openSUSE along the six-month upgrade cycle is too much for them,
and feel they can save time on Ubuntu with the combination of dist-
upgrade and the longer LTS cycle.
The rationale for pursuing this is to revoke the special status of
coolness this functionality gives Ubuntu, and to terminate the negative
- influence that has on our SLE sales (from the expert's personal
- opinion, the preference then spills into purchasing).

This is the #1 feature in the systems management scope for 11.2 - I
have no doubt it will be fun :-)
