I'm upgrading ubuntu from 13.10 to 14.04, during the upgrade it is asking the following question:
Replace the customized configuration file '/etc/sysctl.conf'?
You will lose any changes made to this configuration file if you choose to replace it with the newer version.
Difference between the files:
--- /etc/sysctl.conf 2014-04-21 21:38:34.970070205 +0530 +++ /etc/sysctl.conf.dpkg-new 2013-04-01 07:55:31.000000000 +0530 @@ -1,6 +1,6 @@ # # /etc/sysctl.conf - Configuration file for setting system variables -# See /etc/sysctl.d/ for additional system variables +# See /etc/sysctl.d/ for additional system variables. # See sysctl.conf (5) for information. # @@ -58,7 +58,3 @@ # Log Martian Packets #net.ipv4.conf.all.log_martians = 1 # -# disable ipv6 -net.ipv6.conf.all.disable_ipv6 = 1 -net.ipv6.conf.default.disable_ipv6 = 1 -net.ipv6.conf.lo.disable_ipv6 = 1
I don't understand what this means, I tried googling for an answer but every post has a different file name for the same question and the answers are varying. Should I keep the file or replace it?
