From 8fd1da1a64fc48ccb070bcc52766a547c85cbecc Mon Sep 17 00:00:00 2001 From: Richard Maw Date: Mon, 10 Mar 2014 16:59:07 +0000 Subject: Add sysroot write extension This moves the deployed system to somewhere on the host. Any existing contents of the directory is deleted, so don't try to be clever and deploy a new system on top of / in place of a proper upgrade. It can be used to deploy a chroot, sysroot or container, but its current use is to allow for nested deployments to include another system in itself, since the parent deployment's "$1" is prepended to the sub-deployment's "$2". --- morphlib/exts/sysroot.write | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100755 morphlib/exts/sysroot.write (limited to 'morphlib/exts/sysroot.write') diff --git a/morphlib/exts/sysroot.write b/morphlib/exts/sysroot.write new file mode 100755 index 00000000..1ae4864f --- /dev/null +++ b/morphlib/exts/sysroot.write @@ -0,0 +1,29 @@ +#!/bin/sh +# Copyright (C) 2014 Codethink Limited +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; version 2 of the License. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
