Description Anton Yuzhaninov 2012-11-08 12:40:01 UTC
Some sysctl OID is created only after loading kernel module, where the defined.

E. g. net.inet.ip.dummynet.* sysctls can be set only after dummynet module is loaded.

Fix: To fix 'REQUIRE: kld' should be added to /etc/rc.d/sysctl
But this creates circular dependency, which can be resolved by removing
'REQUIRE: sysctl' from /etc/rc.d/hostid
It seems to be /etc/rc.d/hostid don't not depend on /etc/sysctl.conf settings.
Add to /etc/rc.conf
kld_list="ipfw dummynet"

Add to /etc/sysctl.conf

After reboot this sysctl will no be set.
