[Xen-devel] [RFC][PATCH] create an initrd for dom0 in install.sh script

[Harry Butterworth <harry@xxxxxxxxxxxxxxxxxxxxxxxxxxxxx>]

The attached patch creates an initrd for dom0 during execution of the
install.sh script when the installation is being performed to the root
directory.

I chose the initrd name to correspond with the documentation in the
README file in the dist directory.

It works for me on my ubuntu x86_64 installation but it's untested on
anything else.  I'm guessing that this stuff is probably very distro
specific so it probably not a good idea to actually apply this patch
until it has been tested on some other distros etc.

I'm guessing that the initrd created for dom0 in general won't work for
domU domains.  I'm not sure what to do about that.

Also my script-fu is weak so even what little is here could probably be
better.

Harry.
