Dear All,

rc.conf --> enable/disable system services and daemons
loader.conf --> tunables that can be set ONLY at boot and NOT LATER
sysctl.conf --> tunables that can be set anytime

Some (but not all) sysctls can be set any time but doesn't sysctl.conf only get read at boot?

Yes it does, but later than loader.conf. The main purpose of loader.conf is to load kernel modules.
