Ok, I understand that you want to keep in sync with CVS, but it is
really true that the locales code still changes so often in an
The glibc-$DEBVERSION virtual package which libc6 provides seems very
similar to the shlibs info, which, if I'm not mistaken, it is updated
"when there is a need to". Is there a reason (other than "it's easier")
why the string used for this dependency could not be updated as well
"when there is a need to"?

You are speaking as a i386 user.
This is not so rare for unreleased architectures, since sid is the
*only* existing distribution. In fact, "I'm using sid" is a meaningful
sentence for a i386 user, since he/she could be using woody or sarge
instead. For unreleased architectures it's somewhat meaningless,
since there is no other distribution to choose from.
Currently it's a real pain in the ass to try to install the Hurd from
scratch, or upgrade it, when the locales and libc packages are not in
sync. You have to edit /var/lib/dpkg/status by hand and edit some of
the Provides field.
I guess that the same is true for all other unreleased architectures.
If we do not make unreleased architectures usable enough, they will
never become stable enough to be released. My point is that
unreleased architectures should not be second-class citizens,
as far as useability is concerned.

It's more "users of unreleased architectures", really.

Again, you seem to speak as a i386 user. There is no such concept of
"upgrading to sid" for a hurd-i386 user. They are always running sid,
because there is no other distribution to choose from.
If they are not even able to install sid from scratch, they hardly
will be able to upgrade from the sid-of-yesterday to the sid-of-today.
There is a breakage that you don't see: Say that a hurd-i386 user has
glibc-2.2 and locales-2.2 installed (I'm dropping debversion numbers
for clarity). Say that you upload glibc-2.3 and locales-2.3 for i386,
which are recompiled for hurd-i386, and the day after, you upload
glibc-2.3.1 and locales-2.3.1, which are not recompiled for hurd-i386 yet.
Well, if the hurd-i386 user didn't upgrade to glibc-2.3 and
locales-2.3 the day they were both available, he/she will not even be
able to upgrade from glibc-2.2 to glibc-2.3 the day after, because
that would break locales dependency and apt will not let you to do that.
So, if we want unreleased architectures to be useable, we should
either eliminate "=" dependencies of very popular arch:all packages on
essential-de-facto arch:any packages, or we should create a testing
distribution for them.
If you are not willing to do anything about the dependencies, please
let us agree that a testing distribution is *really* needed.
