Hmmm. It's disappointing that apt didn't know about this. Isn't this sort
of compatibility between packages exactly the sort of thing that it is
supposed to track?
One option in theory would be a massive breaks list in the new libc
package. I'm not sure howwell tools would handle a breaks list with
every package in the archive and there is also the problem that bad
packages from unofficial repos may well end up with the same version as
good packages from the official repo so a breaks can't be written to hit
one and not the other.
Renaming the libc package would be another way to deal with this but
then we'd be stuck with a strange libc package name forever.
Leaving the symlink in place forever would prevent multiarching armel
with armhf.
In summary breaking early adopters who used unofficial repositories was
probablly the least horrible thing to do.
Anyway, I'm still unsure what I should do now. Presumably I will have to do
some sort of apt-get upgrade to replace all packages (or at least all
packages with executables). But I think the first thing it will try to do
is to replace libc again, and delete /lib/ld-linux.so.3. Maybe I should
make the symlink immutable, or something.
AIUI the old file/symlink (depending on just how old the version you
upgraded from was) was removed due to the fact it was no longer in the
package, so further upgrades should not affect your manually created
symlink.
The next thing i'd do is continue upgrading the system as normal
(apt-get -f install followed by apt-get upgrade followed by apt-get
dist-upgrade). From there you have two choices. If you don't care about
multiarching with armel you can just leave your system as it is with the
symlink in place. If you do care about multiarching with armel you will
have to write a script to search for binaries with the old dynamic
linker path and then replace those binaries with fixed versions (the
exact details of replacement will depend on where you got the binaries
from).
