Ok, I agree. But how do you call python routines from the postinstall
scriptlets which run in do_rootfs context? readelf needs to run at
postinstall time because the binary we run through qemu does not
necessarily belong to the same package. Let's take, for example, the
current patchset. You can have a recipe that provides an input method
module and call gtk-query-modules-2.0 binary to create the cache.

If you know a method to do it, feel free to share.

Thanks,
Laurentiu
