Unfortunately I haven't used them so far, but it would help a lot if you
push your ks scripts to a github project.

This would be very beneficial indeed.

I totally agree. As long as there is no way to get the device supported by
the official kernel-aarch64, these images should be considered as unofficial
and/or unsupported. Many devices are still waiting for mainline support status,
so there is the vendor kernel only (The Pine64 doesn't even have a 'vendor'
kernel, only a community kernel based on the Allwiner BSP).

To make it easier to adapt CentOS to a vendor kernel, I'd really appreciate
if someone could provide a list of mandatory kernel options to be enabled.
(otherwise I need to review 1500+ deviations w.r.t. ODRIOD-C2 kernel).
I'd try then to integrate this settings into the default vendor kernel
configuration.

You may start a very similar discussion when you focus on the boot loader...
