Dan Mihai a49d0fb343 rootfs: delete systemd units/files from rootfs.sh 
Move the deletion of unnecessary systemd units and files from
image_builder.sh into rootfs.sh.

The files being deleted can be applicable to other image file formats
too, not just to the rootfs-image format created by image_builder.sh.

Also, image_builder.sh was deleting these files *after* it calculated
the size of the rootfs files, thus missing out on the opportunity to
possibly create a smaller image file.

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
