Hi again. Perpahps last mail was so long and very dificult to understand.
I will try to explain again with a small example.
1.- Create new hook for initramfs-tools
/etc/initramfs-tools/hooks/soundtest
#----------------8<-----------------
#!/bin/sh
PREREQ=""
prereqs()
{
echo "$PREREQ"
}
case $1 in
# get pre-requisites
prereqs)
prereqs
exit 0
;;
esac
# Hooks for loading some kernel sound modules into the initramfs
. /usr/share/initramfs-tools/hook-functions
MODULES="snd-via82xx snd-ens-1371"
for mod in ${MODULES}; do
echo "adding extra sound module ${mod}"
manual_add_modules ${mod}
done
#----------------8<-----------------
Then chmod +x /etc/initramfs-tools/hooks/soundtest
2.- Generate new image
# mkinitramfs -o ./sound-initramfs.gz
# uname -r
2.6.16-1-k7
3.- Next I will uncompress and show that modules aren't into it:
# gunzip sound-initramfs.gz
# mkdir tmp
# cd tmp
# cpio -i < ../sound-initramfs
23276 blocks
# find ./lib/modules/ -name "snd-via82xx.ko"
(NO RESULTS)
# find ./lib/modules/ -name "*snd*"
./lib/modules/2.6.16-1-k7/kernel/sound/core/seq/snd-seq-device.ko
./lib/modules/2.6.16-1-k7/kernel/sound/core/snd-rawmidi.ko
./lib/modules/2.6.16-1-k7/kernel/sound/core/snd-page-alloc.ko
./lib/modules/2.6.16-1-k7/kernel/sound/core/snd-timer.ko
./lib/modules/2.6.16-1-k7/kernel/sound/drivers/mpu401/snd-mpu401-uart.ko
./lib/modules/2.6.16-1-k7/kernel/sound/pci/ac97/snd-ac97-bus.ko
./lib/modules/2.6.16-1-k7/kernel/sound/pci/ac97/snd-ac97-codec.ko
These are the dependencies of our module but the snd-via82xx
snd-ens-1371 aren't in image.
The problem:
This command in /usr/share/initramfs-tools/hook-functions in
manual_add_modules function
modprobe --set-version="${version}" --show-depends "${1}" 2>/dev/null |
awk '/^insmod/ { print $2 }'
show all dependencies of a module name but don't show the module ${1}
This only ocurrs in some modules and in other work ok, I suppose that
nobody insert sound modules in initrd images, but I need sound modules
and many other stuff.
Following patch will force to copy the module name after copy
dependencies:
--- hook-functions.orig 2006-08-21 21:20:14.000000000 +0200
+++ hook-functions 2006-08-21 21:26:31.000000000 +0200
@@ -52,6 +52,15 @@
echo "Adding module ${mam_x}"
fi
done
+
+ # force copy of module modprobe dont show as dependency
+ this_module=$(modprobe --set-version="${version}" -l "${1}")
+ if [ ! -e "${DESTDIR}/${this_module}" ]; then
+ echo "DELETEME, adding module ${this_module}"
+ mkdir -p "${DESTDIR}/$(dirname "${this_module}")"
+ ln -s "${this_module}" "${DESTDIR}/$(dirname
"${this_module}")"
+ fi
+ # end of force copy
}
# $1 is source
The line echo "DELETEME....." is for debug my hack.
I hope that can be included in next initramfs-tools, that it's really a
good project to create some complex things (livecds, thin clients,
etc...)
Bye
