Hello.
I would like ask, why is not working auto-loading of kernel modules with procd using depmod and modprobe?

For example -

I have empty dir /etc/init.d/modules.d <- I emptied it except modules linked from /etc/modules-boot/ and  run this

depmod -a

iptables -A POSTROUTING -t nat -j SNAT -o xx -s x.x.x.x --to x.x.x.x

or

iptables -nvL -t mangle

iptables -t mangle -A OUTPUT -j DSCP -p tcp --sport 5000 --set-dscp-class cs5

AA
every modules which are needed for source nat or for mangling, are auto-loaded.

BB and CC
in better case its auto-load only master modules (but not the inner modules - in case of mangle it loads mod for ip_table mangle but xt_DSCP is missing and wont load automaticaly.)

Why?
