The osbuilder scrips require at least the following options.
- base os (Fedora, Centos, Clearlinux Euleros, alpine are supported today).
- os version.
- agent version

Depending on the base os choosen. It will download the packages from that
OS. Then the kata agent[1] source is downloaded and installed as well. 

The rootfs creation has the option to build the rootfs using docker
containres. So you can build a rootfs without the tools of the base os target.

As stating point we could start to package and ship an image based on
Alpine Linux.

I think is possible at some point move to use the packages of OS  where
the package is being building , but we need a lot more testing to ensure
all work as we expect. Also, we may need to add support for some popular
deb distros ( ubuntu, debian ? ).

As starting point IMO we can just start to ship an image based in a OS like
alpine. That will require internet access and docker (to use alpine
