[PATCH][XM-TEST] Add support for pulling initrd images from a repo

[Paul Larson <pl@us.ibm.com>]

[-- Attachment #1: Type: text/plain, Size: 357 bytes --]

XM-Test takes a really long time to build the initrd it uses for 
testing.  This patch to the Makefile allows you to specify INITRD="url" 
when running make existing to make it download a prebuilt copy of the 
initrd from a repository.  This also updates the README to document the 
change.

Thanks,

 Simply copy the initrd-X.Y.img file into ramdisk/ and then run:
 
    # make existing
+
+Or, you can run:
+   # INITRD="http://url.of.initrd.repo/" make existing
+
+You do not need to include the name of the image itself in the url, 
+however, an initrd with the right name (initrd.X.Y.img) and version 
+number must exist at that location.  The script will determine which 
+version of the initrd it needs and try to download the right file from 
+that location.
 
 This will set up the link so that xm-test will use the existing
 ramdisk.  Next, just run "runtest.sh" normally.  Note that in general,
