@lanodan yeah, but linux 10.x probably almost a decade away still, since Linux tends to go a few years between major version bumps.
But then seeing how many things broke from the zlib 1.2.x -> 1.3 version change doesn't leave me with a lot of hope that everyone will be prepared in time, and of course our experience when Solaris 10 changed uname to 5.10 might have left a few scars...
