Yes, that would be ideal. In fact, we built the image using the same
script, we just need to alter some pieces of software around it (see
my answer below).

Since we need to wait until we get the missing patches in the distro
anyway, maybe we could work something out like building on our side or
running the script I made?

We are missing patches in lorax, virt-manager and
sig-cloud-instance-build, respectively:

https://github.com/rhinstaller/lorax/pull/149

https://github.com/virt-manager/virt-manager/commit/cd35470e3c55aa64976cd0a96a6cfd756f71de17

https://github.com/CentOS/sig-cloud-instance-build/pull/65

Regarding publishing the image to docker registry, I don't think the
same process used for x86_64 would work because ppc images should go
to centos/ppc64le. Like Murilo said in the previous email, we couldn't
find how aarch64 images are pushed to centos/aarch64, there are still
some black boxes we need to understand so that we could do the same
for pcc64le.

It doesn't need virtualization, but that's what is being currently
used for x86_64, is it not? See:

This was meant as future steps, after we have the base image.
