it repeatedly happens that there is a change introduced in the distribution

about it.

Speed of things makes these unfortunate consequenses and side-effects
happen more easy...
It will not be always known in front, unless a depsolver would be run
against those changes, to make predictions of what could break...

But on the other hand: making changes, forces to repair what breaks...

Not saying that it is nice not to know upfront what has going to get

Examples would be the removal of X configuration including keyboard layout
from YaST as a consequence of deprecating Sax2, meaning that it is now not
possible to change keyboard layout for KDM/XDM, or the upgrade of PackageKit
to a newer version that no longer had PolicyKit as a dependency but instead
started requiring its newer and backwards incompatible version polkit-1,
requiring rewritting KDE support from scratch (which is the reason why KDE in
11.2 uses polkit-gnome). In the first case, I don't remember that mentioned
anywhere, in the latter case, the kupdateapplet maintainer was notified
(where it didn't really matter) but not the KDE maintainers. Others could
probably come up with their own examples.

Both consequenses are becoming visible while you wrote your thread. (as
i was told to uninstall packagekit or break it, ignoring unfullfilled
deps...sax2 parts of yast...)

I'd prefer if such things didn't happen again, or at least if they were
in advance. And it even seems doable, because some changes already are
announced, e.g. new gcc version, the switch to linking with --as-needed, etc.

Therefore I want to suggest that announcing important changes in the
distribution that affect other components of the distribution becomes

iirc, stephan anounced the departing of sax2 some months ago in this
very list....
(probably not knowing what the exact consequences were at that moment...)

What would qualify for such a change is somewhat hard to specify exactly,
I'd hope using common sense to judge would do. For example "we remove support
for X settings from YaST and require desktops to take care of these settings
if necessary" or "we introduce new polkit-1, which is not backwards
compatible to the old PolicyKit, and deprecate the old one" are clearly
changes that should be announced. Something like "DHT support in KTorrent is
now enabled/disabled" or "libjpeg is going to be upgraded from 6.2.0 to
6.2.1" is clearly of no interest, as long as it is not known to break other
parts of the distribution - that would just create an unnecessary flood that
nobody would follow.

The place for such announcements would be this list, with some specific
subject to make it easier to spot them (and perhaps some more firm pointing
to the right list would be needed for those who create noise, or something
from would
be needed).


As far as i remember there were always major changes in every new
version, making updating a hell.
Reason to make more clever update clients as zypper's development was a
result of that...
As these changes here, they were announced before the release of the
last milestone of oS11.2, to be progressed in 12..... i guess there is
time enough to deal with the consequences?

(but, i am no authority, nor programmer, these are just plain thoughts....)
