When using rpm however, these are mapped to the rpm "preun" and "postun" events which occur after postinst for upgrades, and when these contain removal type operations (such as update-alternatives --remove) this causes problems. This patch wraps each preun and postun script for rpm in a check that determines whether or not the script is being called during an upgrade, and skips the entire script if it is, which mimics the behaviour of opkg under the same conditions.
