From 1d3f37dc9a43ba6d6beb7b4530c077f239032b99 Mon Sep 17 00:00:00 2001 From: Paul Eggleton Date: Wed, 9 Nov 2011 11:12:08 +0000 Subject: classes/package_rpm: disable uninstall scripts for upgrades Our current assumption (based on the behaviour of opkg) when writing recipes is that prerm and postrm do not get called during an upgrade. 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.
