# HG changeset patch
# User agriffis at cheo.zko.hp.com
# Node ID ecdec03697eab8a622e46755d0330a05694f14f5
# Parent 42e7d064ab2666bad84fc61f0465bee4f7c79d65
Add support for LT_HYPER
This patch adds support for the LT_HYPER line type. Whereas grub uses
kernel=hypervisor module=kernel module=initrd, elilo uses
vmm=hypervisor image=kernel initrd=initrd. Adding LT_HYPER support,
and extending it backward to grub, makes dealing with this a lot
easier.
configFileInfo->mbHyperFirst is added to differentiate between grub
wanting the hypervisor listed first, and elilo wanting the kernel
listed first (image= is the entry separator so it's very important)
configFileInfo->mbInitRdIsModule is added to handle grub wanting the
initrd listed as a module when multibooting
The logic in addNewKernel is considerably rewritten (and cleaned up!)
to be more generic and handle elilo alongside grub.
Additionally one memcpy is corrected to memmove, since it was unsafely
copying overlapping regions.
Grubby builds with this patch and no new regressions are reported by
the test suite.
