I'm not sure why we don't simply unset the LD_LIBRARY_PATH from our main Makefile.

Well, the tarball has been created because your configuration has the tarball image enabled. The other files are normal: bzImage is the kernel image, grub.img is the bootloader, rootfs.cpio is the root filesystem as cpio, and rootfs.iso9660 is the final ISO image, which bundles the kernel image and root filesystem. > The > .iso file size as you've said in your lecture on youtube is only 16 MByte > and not 700 MB like ubuntu official releases.

How can you believe a system generated by Buildroot will install a "customized ubuntu". Buildroot has nothing to do with Ubuntu, Buildroot is meant to build from source highly customized embedded Linux systems. The minimal system only has Busybox (shell and basic command line utilities). Any other component you may want has to be enabled in "make menuconfig". > 2).

We have packages for X.org and Matchbox, which is what Angstrom is using. You'll have to enable them in "make menuconfig". Though be aware that Buildroot is not a tool that builds systems that work out of the box: it merely builds all the packages needed, but there is often some configuration files and other specific customization needed to make everything work properly on a given hardware platform.
