Bug#591325: initramfs-tools: kernel does not boot without network connection

[Євгеній Мещеряков <eugen@debian.org>]

Package: initramfs-tools
Version: 0.97.2
Severity: grave

Recently during boot initramfs started to send DHCP RARP request to all
network interfaces. This behaviour was not observed before and I changed
nothing in initramfs-tools configuration for long time. This can be
because I started to use dhcp for network configuration (using
NetworkManager, and not for network boot boot) or just because I
installed new kernel.

The result is that kernel fail to boot if there is no network
connection, so severity is grave. initramfs just displays repeatedly
messages about timeout and giving up, but does not really give up.
