However, I just remembered that the rpm packages are not installed in
dependency order... So, there might be packages, that need
gtk-update-icon-cache, installed before libgtk+ is installed. In this
case, the postinst scriptlets that test the existence of the binary on
the target rootfs will fail at do_roofts time... Unless a solution is
found to install the rpm packages in dependency order. BTW, is this
planned to be fixed?
