From 7c7a6e75fe96dfcc53f18a90dcd4e3f5ced7cea8 Mon Sep 17 00:00:00 2001
From: Hongxu Jia <hongxu.jia@windriver.com>

Subject: [PATCH] support downloading file from http/ftp server to target image
Add key in kickstart to support downloading file from http/ftp server to target image,
'download --dest=[file://dir/filename|/dir/filename] --src=[http url| ftp url]'
Here is the example in kickstart file:
---start---
download --dest=/etc/rpm/keys/0x100001 --src=http://128.224.162.159/testkey
download --dest=file://etc/rpm/keys/0x100002 --src=http://128.224.162.159/testkey2
---end---
The file be download to target image (/mnt/image/****). For host image,
we could make use of "%pre" section with invoking shell to do that)
Upstream-Status: Inappropriate [oe specific]
