From 9cdb281fa64eb2b58ec1d25cb62c29268aa4b906 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Sun, 3 Jul 2016 17:08:19 +0200 Subject: fs/common: add option to execute custom scripts under fakeroot Some users have the need to be able to tweak the content of the target rootfs with root-like rights, that is, from inside the fakeroot script. Add a new system option to allow those users to provide a list of scripts, like the post-build and post-image scripts, that will be run from our fakeroot script.
