Cole Robinson 4004bd8fbe image-builder: Add NSDAX_BIN for passing in compiled nsdax tool

In Fedora we are running the osbuilder scripts on the client machine,
to generate an initrd for the running host kernel. In this setup,
there's currently a runtime dependency on gcc for compiling the nsdax
tool, which is suboptimal.

Add NSDAX_BIN environment variable; if specified, image-builder.sh
will use that path as the nsdax tool. This let's ship a compiled
nsdax tool to users and drop the runtime gcc dependency

Fixes: #417

Kata Containers image generation

A Kata Containers disk image is generated using the image_builder.sh script. This uses a rootfs directory created by the rootfs-builder/rootfs.sh script.

Creating a guest OS image

To create a guest OS image run:

$ sudo ./image_builder.sh path/to/rootfs

Where path/to/rootfs is the directory populated by rootfs.sh.

Note

: If you are building an image from an Alpine rootfs, see the important note here.

Further information

For more information about usage (including how to adjust the size of the image), run:

$ ./image_builder.sh -h
