Yes, sure, this will work for my own use. But it doesn't solve the
general problem, with pre-built images involved.
What if I want to make a recipe that works on the OpenWrt Buildbots?
The idea was to make first time installation as easy as possible, by
providing both an image that can be installed from OEM and an image that
enables the full hardware.
I did come up with a sort of working proof-of-concept hack, where I add
a build rule like (yes, ugly - I'm not excpecting to push this):
rm -rf $(TARGET_DIR).x
sed -i -e 's,CONFIG_INITRAMFS_SOURCE="$(strip $(TARGET_DIR)) ,CONFIG_INITRAMFS_SOURCE="$(strip $(TARGET_DIR)).x ,' $(LINUX_DIR)/.config
cp -a $(TARGET_DIR) $(TARGET_DIR).x
rm -rf $(TARGET_DIR).x/lib/firmware/qv840 $(TARGET_DIR).x/usr/lib/opkg/info/qv840-firmware.*
I was just hoping there would be nicer ways to do it.
