For gutsy, several of us worked to port all the packages to the
new APIs. I suggest the same for Hardy, only more so. Starting this
before DIF is not entirely useful unless we know there won't be
updates, but initial work is welcome (on the other hand, we
transitioned flac 3 times for gutsy, and I wouldn't want to see that

Someone should write a fix. For each programming language in
which we have packages, we can likely find at least one programmer,
and most FTBFS issues are relatively simple architecture-specific
issues, API changes (where the library authors often provide a
migration guide), or changes in the build tools, which tend to be well

If it warrants removal, yes. I don't imagine we'll need many
removals for FTBFS if we're attentive.

It definitely matters for all supported architecures. Ports are a
little more flexible, although it would be nice if the ports also
didn't show these issues.

I'd like to restrict package removals to things clearly not
useful, rather than NBS/FTBFS/outdated. I firmly believe we have the
skills to fix all of these, as long as we have the tools to track

With the restricted removals I envision, I don't imagine anything
removed should re-enter. As a result, I don't imagine much impact on

I'd suggest it depends on why it was removed from Debian. If it
was just RoM, and someone thinks it really should have been orphaned
instead, I can imagine keeping it. In most cases, I think removed
from Debian likely means should be removed from Ubuntu. Dead upstream
is different: if the package is still useful, and still maintained
(either in Debian or in Ubuntu) I don't see any value in removing it.
As cruft develops, this argument becomes weaker, and after a while
there should either be an alternate solution, an upstream fork, or the
package should be dropped.
> Does the requirement for a replacement also applies to library packages?
Yes, and even more so. Libraries have clients, and the client
packages need to work. I'd really like to stop maintaining libjsw,
but I don't want to remove Search & Rescue. Maybe I'll get around to
porting Search & Rescue to the new joystick interface, or maybe
someone else will. On the other hand, I don't feel we have a
responsibility to support APIs not required by software in our
archive: users with locally compiled or third-party software should be
reviewing the release notes and planning appropriate adjustments as
part of their internal upgrade plans.

Loosely, yes. For any package in Gutsy or Dapper for which there
is a sane replacement in Hardy, we should make best efforts to ensure
that an upgraded system continues to work. While we can't support a
user's local PHP4 code, we can make sure that an upgraded system has a
working apache2/php5 installation when the upgrade is complete, so
that the client can deploy their locally modified php5 code, and
everything just works.
> How automatic should the transition be? What if no automatic transition
I think the goals should be 1) minimum pain, and 2) minimum number
of binary packages not distributed by the archives left on the system.
Sometimes this means providing empty transition packages. Sometimes
there is no good solution. Where we can't do anything, we should at
least have investigated, and draft good release notes. Ideally, users
without custom installed software should be able to continually
upgrade LTS to LTS or release to release and never end up with
anything in "obsolete or local". I'm not certain reaching this state
is possible, but it remains ideal.
