# debootstrap 1.0.76 started creating /dev/ptmx as a symlink to
# /dev/pts/ptmx.  Unfortunately, this doesn't work with sbuild, because it
# leaves the ptmxmode mount option at its default of 000, which causes
# builds to be unable to open /dev/pts/ptmx.  To avoid this, debootstrap
# 1.0.89 switched to creating it as a device node where possible.  See
# https://bugs.debian.org/817236 for details and analysis.
#
# xenial has a version of debootstrap in the range that contains this bug.
# It seems too risky to try to cherry-pick the debootstrap change in
# question in an SRU at this point; instead, just fix things up here for
# buildd images.
