Hi,

I need to load some extra modules "manually" when
my Linux box boots to get access to an embedded 
system. These modules need to be added to 
/etc/conf.d/modules for various reasons.

The modules are:

ipt_MASQUERADE          1037  2 
nf_nat_masquerade_ipv4  1785  1 ipt_MASQUERADE
iptable_nat             1578  1 
nf_nat_ipv4             4811  1 iptable_nat
nf_nat                 11442  2 nf_nat_ipv4,nf_nat_masquerade_ipv4
nf_conntrack_ipv4      11964  1 
nf_defrag_ipv4          1395  1 nf_conntrack_ipv4
nf_conntrack           61998  4 nf_nat,nf_nat_ipv4,nf_nat_masquerade_ipv4,nf_conntrack_ipv4


How can I distinguish those modules from this list, which need 
to be listed in /etc/conf.d/modules from those, which get pulled in by
these?

Best regards
mcc

First it does no harm to load modules directly which would be pulled in as dependency anyways.
From the the above lsmod you can leave out those, which have a nonempty used by column. That would be

   ipt_MASQUERADE
   iptable_nat
   nf_conntrack_ipv4

To get more complete information on dependencies you can look at

    $ modinfo ipt_MASQUERADE

etc. However to get full information you have to look at

    $ cat /lib/modules/$(uname -r)/modules.dep

This gives a complete list of dependencies.
