In order to make the building of the ISO non-reliant on any sort of
external settings from the build system, the kernel source for needs
to be populated into the chroot, along with the pre-made kernel config.
Previously, if you were to boot this image you would be greeted with
an error message telling you that the background could not be set.
To fix this the package eterm was added to the fluxbox world file
to be pulled in on build-time. However, this only solved the problem
of being unable to set the background manually. To have fluxbox set
it automatically the .xinit was altered to call "exec startfluxbox".
When fluxbox is called by that command it searches for and executes
the startup file located in ~/.fluxbox/. This commit also adds a
custom startup file which sets the background to the default background:
/usr/share/backgrounds/background.jpg. This commit also includes one
unrelated alteration to fluxbox-run.sh which changes the fluxbox init
file to look at the custom menu in /usr/share/fluxbox/usermenu instead
of ~/.fluxbox/my-menu.
The Fluxbox menu can either be a standard default or a custom file. While
there is already a custom menu file in existance under files/usermenu, it
was not previously being copied over prior to the creation of the ISO. This
caused the user to not have a custom menu file upon boot. To fix this, a line
has been added to the script which creates the .fluxbox directory prior to
building the image.
