We had a discussion about this on IRC, a while back, let me see if I
If we continue to use libc6 as the package name as we're currently
doing, at some point libc will get upgraded to the NPTL interface and
things will start crashing immediately. I asked if we could just do
"whatever x86 did", and kyle said that we have a problem they didn't -
our data nptl/lt data structures are incompatible.
We can deal with that to an extent by adding a second libc package,
e.g., libc6.1. But, jejb pointed out that, since most libs depend on
libc, we'll need to be able to have libs for both interfaces at the
same time to support a transitional upgrade - and that implies an
SONAME bump for every C library.
Hopefully there's an easier way, but I don't know of one.
