Hi, this check just broke the dist-upgrade of my server, going from jessie to stretch.
While my machine is a vserver with a kernel 4.4.268 which is not part of the Debian OS that I control, the current Debian kernel in stretch is 4.9.290-1 if I'm not mistaken, so I guess it's also affected. So it looks to me like this is breaking any updates of glibc in stretch? But breaking updates in a vserver scenario like above is also bad IMO. I'm not sure if the preinst check is entirely obsolete, but if not, it may at least additionally check if the current kernel has the version clamping fix by upstream applied[1], which is true for -stable versions >=4.4.257 and >=4.9.257.
