[BusyBox] Module autoloading in a busybox/uClibc environment

[Lars Kellogg-Stedman]

Howdy folks,

I'm having some difficulty getting kernel modules to autoload as I 
expect (busybox cvs + uClibc cvs as of this weekend).  For example:

  ~ # vconfig add eth0.200 200
  WARNING:  Could not open /proc/net/vlan/config.  Maybe you need to 
load the 8021q module,
or maybe you are not using PROCFS??

On my RedHat 9 system (and on other "full" distributions), this would 
correctly load the 8021q kernel module.  Similarly, the following also 
fails:

  ~ # iptables -t nat -nL
  iptables v1.2.9: can't initialize iptables table `nat': Table does not 
exist (do you need to insmod?)

Again, the behavior I expect is for the necessary modules to be loaded 
automatically.

I'm running module-init-tools 3.0pre9.  'modprobe' run manually from the 
command line works just fine:

  ~ # lsmod
  Module                  Size  Used by
  ~ # modprobe iptable_nat
  ip_tables: (C) 2000-2002 Netfilter core team
  ip_conntrack version 2.1 (5120 buckets, 40960 max) - 296 bytes per 
conntrack
  ~ # lsmod
  Module                  Size  Used by
  iptable_nat            20516  0
  ip_conntrack           29856  1 iptable_nat
  ip_tables              17680  1 iptable_nat

And /proc/sys/kernel/modprobe contains '/sbin/modprobe'.   All the 
kernel modules are available (that's why they load just fine manually), 
and modules.dep is current.  I'm not sure where else to look, so I'd 
appreciate any pointers.  Thanks!
