# fixes "# mesg: ttyname failed: Inappropriate ioctl for device" warnings when building docker
#
echo '#! /bin/sh' > /usr/bin/mesg
chmod 755 /usr/bin/mesg
# all this does is replace the 'mesg' command with a no-op that always succeeds.
# do this *early* in your Dockerfile somewhere.
# from a security persprective this is also fine because it relates to multi-user unix systems,
# not single user/contrained docker images.
