Early image startup
I have a Poky image which uses a number of kernel modules. For whatever reason, the raw image has not had the modules configured (no /lib/modules/.../modules.dep) This file is created by 'update-modules' but that is run too late in the boot process. The problem is that other code, e.g. I'm using iptables via modules, requires the modules be configured early and this fails. If I reboot (after 'update-modules' has run), everything is fine.
My system is PowerPC and I'm using ipk packaging.
Here's a snippet from my initial boot log:
Please wait: booting...
Starting udev
Configuring network interfaces... udhcpc (v1.17.3) started Setting IP address 0.0.0.0 on eth0
Sending discover...

Deleting routers

modprobe: can't open 'modules.dep': No such file or directory
iptables v1.4.9: can't initialize iptables table `filter': iptables who? (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded.

Configuring update-modules.
Configuring kernel-image-2.6.37.3.
Configuring kernel-module-nf-conntrack.
Configuring kernel-module-x-tables.

Configuring kernel-module-ipt-masquerade.
Configuring kernel-module-iptable-nat.
Configuring kernel-module-iptable-filter.
Configuring netkit-tftpd.
Configuring kernel-module-xt-tcpudp.
So, what decides when these 'configuring' steps run?
Thanks

FAOD, these are my init.S steps:

Sound like you need http://patches.openembedded.org/patch/1917/

To be honest that sounds like a more fundamental problem as if the user cares which rtc should be rtc0, there are other ordering constraints being imposed such as a symlink to the "best" rtc device...

Indeed, this patch did not help my situation at all.
I think my problem is that of post-install package scripts (hence 'Configuring ...') not being run until quite late.

Looking at the pre-run image, I see that there is /etc/rcS.d/S98configure which runs these scripts. Is there any reason I can't move it earlier?

Found it:
ipk systems - meta/recipes-devtools/opkg/opkg_0.1.8.bb rpm systems - meta/classes/rootfs_rpm.bbclass
Note: the ipk version is quasi-configurable, the rpm version hardwired at 98. Since these are package install scripts, which presumable could have been run at image creation time but needed to run on the target hardware, why put it off to so late? I would think that this should be done _first_, not _last_

As for the rpm ordering this was preserved from an earlier version. If there is a more appropriate place to run the late configuration scripts, let's move it. I think that it's likely a good place to move it to soon after the filesystem has been mounted RW. Do any of the scripts normally require networking or other system resources?

Hard to say what's perfect, but I certainly don't believe that they need
to be put off to the very last. In any case, I think the best thing is
to make it easily adjustable, per my patch.
Can we please keep this discussion on the Poky list where it started? It seems that OE (and maybe OE-core) handle this differently - I've not looked in depth - and I'm mostly interested in getting my Poky builds healthy.
