Thanks for the reply. What I'm not understanding is how I can invoke my
shell function. Do you mean
I have to invoke it as append function of populate_rootfs one? What I
really need is a way to query the rpm database
out from the build system, as we normally do with host packages.
I tried to have a standalone run of  the rpm command the
list_installed_packages invokes but (obviously) I got a long series of
errors.
