Arch Linux

Don't know if it helps, but for now I'm using this code to include the firmware files:

for i in `modinfo $MODULES | grep firmware: | gawk '{ print $2 }'`; do
[ -f "/lib/firmware/$i" ] && add_file "/lib/firmware/$i"
done

I also don't know if modules with missing firmware should be removed from $MODULES again.

Okay, this sounds good, however, you need a -k option with modinfo (the kernel version you are running is not always the one you are building for). This should be included somewhere with the add_module function so that any module that needs firmware will have it included.

I hope to be able to work on mkinitcpio soon, there is so much to do here.

At first I thought so, but I didn't know where I can get the target kernel version. As $MODULES contains the complete paths to the modules this should not be necessary, should it?

here my suggestion:

attached patch

One problem still exists:
ipw2200 and ipw2100 don't list firmware at all in module.
Don't know if more are affected.

Other point:
Are those listed firmware files the correct ones?
iwl packages provide more then one firmware file but only 1 is listed in modinfo.

You're right, it seems that some modules don't list their firmware.
Well, for the e100 module your patch is working perfectly.
I'm not sure if anyone wants WLAN in initcpio. ;)

tpowa, that patch should work perfectly - I was wrong about needing -k, as we specify the full path to the module! Also, the -F firmware simplifies this considerably (much less parsing to do in bash scripts). Move it in.

About modules without firmware entries: There is simply nothing we can do - we act on the information we have. If there should be a firmware listed for a module but isn't, it's a kernel bug and should be reported as such.
