when $DEVICE is not set (which is now default), otherwise ipconfig may
receive a valid DHCP response, but fails to break out of the loop and is
called repeatedly.
thanks to Petter Reinholdtsen, i think i've figured out the
initramfs-tools portion of this problem (there may still be outstanding
issues with ipconfig).
tested the attached patch, which seems to address the issue for me at
least.

version is "the" essential exported variable by mkinitramfs.
Use it's string length to determine that we are on mkinitramfs stage
and not trying to boot a not precached initramfs image.
hook scripts on boot can exit due to random failures and shouldn't
interrupt boot there.

MODULES=dep fails when / is ubifs. This patch adds support for
something like root=ubi0:rootfs when ubi is modular.
Quoting Martin:
It essentially does three things:
- adds the correct modules to the ramdisk (for MODULES=dep and MODULES=most)
- reads ubi.mtd= from the command line
- loads ubi with the ubi.mtd info and ignores the "Waiting for root" check
I've successfully tested this with a kernel with modular ubi and with
the following boot variants:
console=ttyS0,115200 ubi.mtd=2 root=ubi0:rootfs rootfstype=ubifs
console=ttyS0,115200 ubi.mtd=2 root=ubi0_0 rootfstype=ubifs
With
console=ttyS0,115200 ubi.mtd=2 root=/dev/ubi0_0 rootfstype=ubifs
I get an error that it cannot mount root but I suspect this is an
ubifs error and has nothing to do with i-t (since at this point I can
manually mount it with -t ubifs ubi0_0 whereas the /dev/ variant
doesn't work).
Tested with MODULES=dep and MODULES=most as well as with a kernel that
has ubifs built in.

initramfs-tools currently requires a device to be hard-coded, but this
is not much use if the network device is not known ahead of time. If
the device specified in either /etc/initramfs-tools/initramfs.conf or
on the ip=xxx kernel command line.

Here is a bug description and a patch. Please consider it.
The patch solves a an LTSP client problem that arises when
the clients are connected to Cisco switches that have
spanning-tree calculations enabled.
Also related to:
http://git.debian.org/?p=kernel/initramfs-tools.git;a=commitdiff;h=9c3ec61b1a5e2feaa8d9c6de737eaa00eb446a9c
And
http://git.debian.org/?p=kernel/initramfs-tools.git;a=commitdiff;h=115134f07a0dd042355a2a6fb5a5ca987b000f5d
Here in an extensive explaination:
https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/181258
Also in the following:
I can report the same problem. A number of diskless clients go
flawlessly through a PXE boot, then the net interface is brought down
when the Linux kernel boots and suddenly, dhcp does not work anymore.
Background research on the network: The clients are connected to Cisco
switches. The configuration of the switches makes them run spanning-tree
calculations. This usually takes some seconds but for large networks it
can take up to 30 40 seconds.
The network port on the switch is turned on, when this calculation has
been finished. This is primarily a security measure.
See also: http://networkers-online.com/blog/2008/08/what-is-bpdu-filter/
If this security measure is turned off, the client boots without
problems. :)
To debug the problem, the following boot line was used:
kernel amd64/vmlinuz
append ro initrd=amd64/initrd.img nbdport=2000 debug=100 break=1
ip=dhcp
In my case, this causes a timeout as can be seen on the attached
screenshots. The kernel loads the NIC module e1000e and reports the type
of NIC et.c. The kernel time reported is 5.927 .
The debug shows the following:
configure_networking
[ -n eth0 ]
[-e /tmp/net-eth0.conf ]
ipconfig -t 60 eth0
At about 6.4 in kernel time, the NIC module reports further about it's
IRQ configuration.
Two seconds (2 sec) later at about 8.56 the NIC module reports that the
Link is up at 100 Mbps full duplex.
Some milliseconds later it signals ADDRCONF(NETDEV_CHANGE): eth0: link
becomes ready .
At this point in time, ipconfig is just waiting for an answer to the
DHCP-discover that really was choked by the switch.
Now this is an obvious flaw in the script. It would be much more
reasonable to try repeatedly with increasing timouts. This would also
be much more efficent.
may I suggest the following timeouts:
4
8
16
30
60
The sum of this timeout is about 120 seconds.
I did some testing with exponential timeout with 1 2 4 8 16 30 ...
and it solved the problem, but it seems that ipconfig runs once
additionally after it has actually done the job.
I am running tests now with an exponent of n/1.5 instead of n.
That would give a sequence of (ca)
2 3 4 6 9 16 25 36 64 100
Attached are a jpeg screenshot of the boot sequence and of
course the patch. The patch is relative to the present git
snapshot.

Since fstype does not support btrfs (#548047),
and since udev 150, vol_id no longer exists,
get_fstype sets FSTYPE to "unknown", and
then the root filesystem is mounted using
"mount -t unknown /dev/hda2 /root".
Of course, that fails, and with a really unhelpful error message
("mount: device doesnot exist")
Why not just skip the -t parameter if FSTYPE=unknown?
Mounting the root fs was going to fail, so letting
mount autodetect the fs type can't be worse.
Attached patch does that and got my root on btrfs working.
Workaround: boot with rootfstype=btrfs

The i915 DRM module doubles as a framebuffer of sorts, at least in kernel
mode-setting setups; like its cousins intelfb and i810fb, it effectively
requires intel-agp despite not actually using any of its symbols. As
such, could you please arrange for scripts/init-top/framebuffer to give
it the same treatment, per the following patch?:

After further experimentation, I discovered additional problems that my
first patch did not address, namely that
1) Some FB drivers need the AGP subsystem up and running before they
are loaded and
2) intelfb needs intel-agp.ko, but does not have a dependency on it.
intelfb does not actually *work* on my testsystem after this (it
crashes), but unlike with plain initramfs-tools, it loads (and prints
something useful if loaded with the probeonly option). I'll try to find
out why it fails to work tomorrow; it's probably an unrelated issue.

while at it cleanup the variable name that came due to legacy
naming nfsopts in a very early initramfs-tools release.
"The local-top/iscsi initramfs integration script uses the
configure_networking function, which depends on the IPOPTS environmental
variable set by the init script. However, this variable is not
available, because it's not exported from init, and local-top/iscsi is
not sourced but executed. Thus static IP configuration on the kernel
command line is not communicated to the script."

The attached patch is needed for booting with root=mtd0.
Basically, the init scripts assume the root device should have a special
device file somewhere, and if not will wait for it to appear. This patch
changes it so that it only waits for a device file to appear if $ROOT starts
with "/dev". In the case of things like ROOT=LABEL=foo, the init scripts
will translate that to a device. With ROOT=mtd0, the init scripts will not
check for a device, and will successfully mount the root filesystem.
