There already may be a file there for the purpose, maybe better to take a looksee first instead of
possibly blindly overwriting:
####
#
# /etc/sysctl.conf is meant for local sysctl settings
#
# sysctl reads settings from the following locations:
# /boot/sysctl.conf-<kernelversion>
# /lib/sysctl.d/*.conf
# /usr/lib/sysctl.d/*.conf
# /usr/local/lib/sysctl.d/*.conf
# /etc/sysctl.d/*.conf
# /run/sysctl.d/*.conf
# /etc/sysctl.conf
#
# To disable or override a distribution provided file just place a
# file with the same name in /etc/sysctl.d/
#
# See sysctl.conf(5), sysctl.d(5) and sysctl(8) for more information
#
####
To me, "on boot" implies something on the kernel cmdline, e.g.:
ipv6.disable=1
Even using that I sometimes find ipv6 errors in dmesg that can be cured via an avahi config change.
