so files/ only contains generated stuff.

This Separates files we want to upload (needed to build the image) from
files in this repo and temporary files like logs before things get out
of control.

Otherwise calling make on an aborted image build will compress
it instead o rebuilding it

so not every function has to bother with the proper setup.

It's not needed on the nitrogen boards and the losetup sometimes
confuses the build if vmdeboostrap was interrupted forcefully.

Old Boundary uboot cant read from ext4 and so we need ext2 for the
initial uboot update. Also we want separate /boot to turn on disk
encryption.

There passed down to vmdeboostrap explicitly anyways since sudo
might clean the environment.

It's currently not used

to not leave traces on the host system

While we could install some in root.sh and some in lava.sh having
this in one place makes it easier to debug and since we're past
debootstrap it's more robust.

This adds a function which runs apt-get inside the generated image to
install task-gnome-desktop.  Apparently debootstrap can't handle
this.

GNOME is a massive addition so it's commented out for now as it's
probably overkill unless needed.

since gogs runs into a timeout otherwise.  See

This will allow us to use shallow clones

rather preprocess the boot files

so we rebuild properly on errors

to disable LVDS/LCD

so tools like curl etc have a trusted certificate store

makes using external SSDs and such simpler

Do this via separate variable so it can be disabled easily and we can
put this into an image flavour later.

so he/she can launch it from the console

Bind mount qemu-arm-static so we can run commands inside the chroot

Do this via separate variable so it can be disabled easily and we can
put this into an image flavour later.

We store the uboot update in a subdirectory

so one can see progress during the image write

Change the instructions back to using the mainline kernel

We need ti-connectivity firmware for the WiFi chipse

This gives us HDMI and it's a one line change to switch to another
kernel.
