The question is why did you do that initially? Because of a failed

Actually ldconfig creates links for 2.11.2 files in /lib. We have a
script to detect old ld.so in /lib, it looks like we have to extend it
for all files from libc6.

If we consider that the installation scripts should fix files that
should not have been there at the first place.

Given you had a very strange system, I would suggest to run: 'apt-get
install --reinstall libc6''
