# Make HipChat grsec friendly
#
# To build the Docker image, I currently had to disable the following grsec protections:
# # grep -E "chroot_deny_chmod|chroot_deny_mknod|chroot_caps" /etc/sysctl.d/grsec.conf
# kernel.grsecurity.chroot_deny_chmod = 0
# kernel.grsecurity.chroot_deny_mknod = 0
# kernel.grsecurity.chroot_caps = 0 (relates to a systemd package)
