RE: [Xen-ia64-devel] RE: [elilo-discuss] a patch to make elilo loadanother module

["Magenheimer, Dan (HP Labs Fort Collins)" <dan.magenheimer@xxxxxx>]

Finally got a chance to look at this.  There were a typos
of problems in the README script:

- rpc2cpio -> rpm2cpio
- remove "patch -p2 < elilo-initrd-size-fix.patch"

The resulting source got a couple of gcc errors
with find_label having too few arguments.  I added
module_name as the last argument (two places) and
it compiled.

However, I realize I don't know how to build a RHEL4
kernel (with Xen mods) and initrd that will successfully
boot a RHEL4 system (e.g. with LVM in the initrd?)!
I assume you have done it so far on VTI with an
unmodified RHEL4 kernel?  Unless you can provide a
recipe for this, I will look into how to do it...

Also, I think Anthony had an update for the Xen hypervisor
patch (with the complicated arithmetic with constants
put in a macro)?
