Dear Maintainer,

I'm trying to netboot an x86 system which has multiple NICs, though only
one is recognised by the BIOS/PXE boot firmware and as such the full
netboot process should happen over this interface. However, during
early-userspace live-boot attempts to probe a set of NICs which may or
may not contain the one used for PXE due to seemingly variable delays in
the NIC becoming available.

To reliably boot from the PXE-chosen bootstrap interface PXELINUX supports
appending BOOTIF=<MAC> to the kernel commandline which in-turn has some
support in live-boot. Using live-boot-3.0.1-1 (wheezy) I've observed
that the corresponding BOOTIF environment variable in early-userspace
does not contain a value that looks like a MAC, let alone the MAC of the
bootstrap adaptor.

Investigating, it appears the assignment of BOOTIF in
/lib/live/boot/9990-cmdline-old is inconsistent with other variables.
Attached is a patch that makes the assignment consistent and
successfully extracts the MAC provided on the kernel commandline.

The system information provided below is not relevant to the bug,
however this is the first bug I've reported against a Debian package so
I'm going to leave it.
