Package: initramfs-tools
Version: 0.85h
Severity: normal
Tags: patch
If I want several computers to boot from the same ramdisk (with NFS
root) and some computers have multiple network interfaces, the DEVICE
variable can't be set to a specific value (e.g. eth0). Ipconfig from
klibc supports a mode, where DHCP request is sent to all interfaces
and the one receiving the first DHCP offer is used. This perfectly
suits my needs, but it can't be used with initramfs scripts because
the interface name in not known in advance and the DEVICE variable is
set to something like ::::::.
I have used the following patch to solve it:

if [ "x${NFSROOT}" = "xauto" ]; then
The bug is also present in unstable, but I didn't test this patch:

Please note, that Debian version of klibc-utils contains a bug (see
http://www.zytor.com/pipermail/klibc/2008-February/002209.html) so I
use a patched version.
