Question CONFIG_NF_CT_ACCT: Connection tracking flow accounting disable or...not

uname -r
tells me i am running kernal version

/var/log/syslog says:
CONFIG_NF_CT_ACCT is deprecated and will be removed soon. Please use nf_conntrack.acct=1 kernel parameter, acct=1 nf_conntrack module option or sysctl net.netfilter.nf_conntrack_acct=1 to enable it. says:
CONFIG_NF_CT_ACCT: Connection tracking flow accounting

If this option is enabled, the connection tracking code will keep per-flow packet and byte counters.

Those counters can be used for flow-based accounting or the `connbytes' match.

Please note that currently this option only sets a default state. You may change it at boot time with nf_conntrack.acct=0/1 kernel parameter or by loading the nf_conntrack module with acct=0/1.

You may also disable/enable it on a running system with: sysctl net.netfilter.nf_conntrack_acct=0/1

This option will be removed in 2.6.29.

If unsure, say `N'.
i am "unsure" out of sheer ignorance. Why would i EVER want/need/use "flow-based accounting or the `connbytes' match"?? If i don't know what this means, is it safe to say i will not need it?

Additionally, what steps do i take to "change it at boot time with nf_conntrack.acct=0/1 kernel parameter or by loading the nf_conntrack module with acct=0/1"???

[SOLVED] CONFIG_NF_CT_ACCT is deprecated

Over a decade later is better than never (and this message still comes up in dmesg; "uname -r" = 2.6.32); to turn off:
sudo pico /etc/sysctl.conf (substitute nano for pico if you don't have that editor)
added "net.netfilter.nf_conntrack_acct=0" to the bottom
control "x", "y", enter
sudo shutdown -r now

note: had to add "nf_conntrack" to /etc/modules (new line at bottom, use pico or nano), as above wasn't working (yet "sudo sysctl -p" after it was booted up would switch it to "0"; so, there was some sort of startup order that wasn't timed right for this).

also note: you still have "CONFIG_NF_CT_ACCT is deprecated" in dmesg (assuming that's up to a future kernel to actually stop using, not just threaten), but at least it's turned off (and I'm with you: not sure if I ever want/need/use, but you can easily turn it on by switching it to "1").
