/etc/ld.so.conf and /etc/ld.so.conf.d/* mismatch

I cannot see, how the lib32 directories are inserted in /etc/ld.so.conf, however I only have a system upgraded from dapper, not from breezy.

I wasn't really worrying about the lib32 directories (though now I think about it, that's rather odd too), but rather suggesting that either the include line in /etc/ld.so.conf should read:

include /etc/ld.so.conf.d/*

Or probably better, that /etc/ld.so.conf.d/x86_64-linux-gnu should instead be named /etc/ld.so.conf.d/x86_64-linux-gnu.conf so that the existing include line actually reads it. That's more robust against editors which leave backup files behind.

Does your system have the same "include" line as mine in /etc/ld.so.conf?

I saw a similar issue after a from scratch feisty i386 installation:

/etc/ld.so.conf contains:
include /etc/ld.so.conf.d/*.conf

And inside /etc/ld.so.conf.d, I can see:

i486-linux-gnu

So I guess this file won't be included

I was faced with the problem some seconds ago now. I was very suprised that the libraries mentioned in /etc/ld.so.conf.d/ where not found and then saw the file name problem.
Is there a decision about the names of the files?

I've just tried bootstrapping chroots for gutsy i386 and amd64 (using debootstrap --variant=buildd). In both cases, this mismatch still occurs.

This bug was fixed in the package glibc - 2.7-9ubuntu1
