QA:Testcase Anaconda updates.img via URL

Description

This test will verify that anaconda can download the requested updates.img file using a HTTP url. For help preparing an updates.img, refer to Anaconda/Updates

How to test

1. Prepare a valid kickstart file and copy to a httpd server accessible by your installation
• A suggested approach is to create a dummy updates.img with a empty file

mkdir /tmp/updates
dd if=/dev/zero of=updates.img bs=1k count=1440
mke2fs updates.img
mount -o loop updates.img /tmp/updates
touch /tmp/updates/TESTING123
umount /tmp/updates

2. Boot the installer while specifying the http URL for the updates image. For example:

   updates=http://rhe.fedorapeople.org/install/updates.img

3. Proceed with installation

Expected Results

1. Anaconda prepares the updates.img and copies it's content to /tmp/updates/
2. Anaconda proceeds to stage2 without error
