Re: [F8/multilib] {,/usr}/{,s}bin64 (was: Split libperl from perl)



I'm removing all your references on masturbations and characterizing
me as a kook and the like. Please don't readd them or any other new
non-adolescent vocabulary.

No, you wrongly quoted my 14% as confirming the validity of your
estimation, which I now repeadetly explained that this is not the
case. All it was was an exact number of the set of specfiles *you*
specified as relevant which is not the set of specfiles that would
need modification.

So if you say everything here is fruits and there are 10% apples, and
I tell you, that we need to count oranges, which is a much higher
number, but anyway there are 14% of apples around here, you conclude
that I verified that we only need to count apples, and that 14% is the
correct number. Don't compare apples and oranges.

Hope this analogy makes it clear.

Really think this through to the end including your suggested user use
cases. Do so, and then check what the bin swapping will cause. Or just
read the example below if it doesn't strike you.

And the suggestion to split all bins into sub-sub-packages is just
such a easy short-term solution. Even if we magically get the split
done or ignore the required man time it

o creates file conflicts in the repo by design
o thus borks yum, anaconda, smart and apt
o Requires users to redownload packages each time they wish to simply
  switch from foo-32 to foo-64
o Breaks the majority of config files (that's where the 59% come from)

Remember, you apples, me oranges.

If you allow for your scheme to nuke config files, sure. But that's
not what we'd like to have.

Then watch how switching from foo-32 to foo-64 undoes the users' config.

I _never_ _ever_ did say that the only thing we would have to do is
seperate bins from libs. So this is not something new, for me it was
clear from the beginning that your model will have to evolve to
sub-sub-packages containing only bins, and I wrote that a miriad
times, but you were reading over it.

Examples do seem to work better, so let's try once again.

# foo
<the 64 bit version doe not work as expected, let's try the 32 bit version>
# yum remove foo
foo is required by bar, baz, barbaz, bazbar, ...
[Y,n]: n
<rant, rant, rant>
# rpm -e --nodeps foo
/etc/foo.conf is saved as /etc/foo.conf.rpmsave
# yum install foo.i386
<wait, wait, wait>
# foo
foo has not been configured
<huh? rant, rant, rant>
# mv /etc/foo.conf.rpmsave 
# foo
<ok, doesn't work in 32 bits either, let's switch back, argh ...>

So a short-sighted, short term solution once again. you want to do it
"right"? You need to make sure the bins don't get packaged together
with config files. So that does explode the 14% of just-need-to-split-
bins-and-libs to a higher number, right?

Not making up anything, just pointing to the flaws of your proposal.

Apples and oranges once again. No change of rules, you always read
over my posts, why did I say that every subpackage needs to split out
the bins into sub-sub-packages from the very beginning?

The above example and all others used yum. And yum does get very angry
if there are packages in it's repo-world that conflict on file level.

Heck, we even had a guideline rule created exactly for that: Every
file conflict needs to be made a package conflict, because yum
(rightfully) doesn't like that. And that would not be even possible
with your scheme because Conflicts: does not take an arch.

So, the proposed sub-subpackaging of bins is flawed from all
corners. And the resitance you're feeling from me and seems to make
you angry and offensive is just the preview of what rpm and yum
maintainers will greet you with once they realize that your scheme
needs them to rewrite their tools.

No easy short-sighted and short-term solutions was your slogan, stick
to it.
