From 630a1e0551f0431f8d513f979198ee752653a5e3 Mon Sep 17 00:00:00 2001 From: Chen Qi Date: Wed, 13 May 2015 14:40:09 +0800 Subject: populate_sdk_ext: set noexec flag for some tasks For the SDK, what we are interested in is the sysroot part. So the only useful task is do_populate_sysroot. Other tasks like do_package don't need to run. So mark them as 'noexec' for SDK. This would result in two benefits: 1) The size of extensible SDK is larged reduced. For example, extensible SDK for core-image-minimal is reduced from 1.8G to 793M. 2) The installation time is reduced as a lot of tasks are not run.
