- traceroute
- mtr
- iptraf
- quagga

The linaro toolchain creates files with some obscure user/group.
Instead of trusting the owners/permissions of the downloaded
archives, recursively set all /opt to root:root. If for some
reason any files are setuid, this will also clear that bit.

If building the image from a machine other than nereus, the name
nereus (used in fine-tuning wget) cannot be resolved. Use the
FQDN instead. That works (as long as you are in the Linutronix
network).

Normally the console font and keyboard is setup on first boot.
But this can be done in the finetuning so that we do not rely on
a "first boot" for the console to be setup correctly.

Most of the firmware packages have versions in stretch backports
that support more hardware. Use these in an attempt to work for
all laptops.
NOTE: There are a few firmware packages that are not in stretch
backports. These are still taking from stretch.

It seems that calling umount directly after mount can lead to a
busy error. With strace on umount the problem goes away. It must
be a very small window. Someone should debug the umount syscall
on this. It is reproducable with:
./dd-multi.sh lx-trainer.img /dev/sdx
(i.e. regular training image and no layers)
Implement a workaround for this for now.
From the comments...
If there were no layer files added, umount might return a busy
error since we just mounted. (Possibly a kernel bug.) By
accessing the filesytem before unmounting it, the mount/umount
problem seems to go away. Use "ls" to access the filesystem.

Start the untar processes in parallel. This will take advantage
of file caching and should max out the USB bandwidth.
This is important because some trainings (like Yocto) have huge
layers.

Tarballs are copied to the USB drives and then unpacked in a
chroot. However, this means the data will travel across the bus
three times! For large layers this is craziness.
Since --numeric-owner is used anyway, just unpack the tarballs
directly.

In order for the qemu arm vm's to nfs root out-of-the-box, either
the client must specify v3 or the server must restrict itself to
version 2. Rather than expecting special arguments from the client,
force the lx-trainer image to use nfs server version 2.

Initially write 10MB of 0's instead of 1MB to make sure any tables
at the beginning are really gone.
Rather than calling 'partprobe' with no arguments, explicitly pass
the list of devices to re-read.
'fdisk' is used to create the 2nd (/home) partition. Do not do that
in the background but instead synchronously for each device. Add a
'sync' afterwards to hopefully create a barrier before rescanning
the devices. This is should address a problem where 'partprobe' is
run too early and the kernel does not find the 2nd partition of the
last device.
