Comment 12 for bug 1842437

The problem is reproducible in the sbuild-launchpad-chroot for xenial/amd64,
using the source package for util-linux currently in xenial-updates
(i.e., no regression from debdiff, as expected since changes/error are unrelated)

The minimal command-line for that is:

$ /build/util-linux-kzgHhT/util-linux-2.27.1/script -c echo Hallo World /dev/null </dev/null >/build/util-linux-kzgHhT/util-linux-2.27.1/tests/output/script/buffering-race

script: openpty failed: No such file or directory
Terminated

There was a suspicion about the kernel version difference/regression (4.4.0-159 and -161),
but that's was not the root cause of the issue.

Looking into other areas.
