In particular, the kernel does not use EFI services for the root filesystem. At one point I did take a quick look at the differences between Ventoy's 11.x/12.x/13.x kernel module source and my recollection is that the differences are just typical accommodation for kernel KPI changes. With where we are in the 14.0 release cycle the only thing to do is have support appear via a Ventoy update. Ventoy is a very interesting project though and I would like to look at consistent and maintainable FreeBSD/Ventoy support in the future. This could be done either by continuing to use geom_ventoy but bringing it into our release (via a port or in the base system), or possibly by having the release images support mounting the cd9660 root filesystem image from a file in an outer filesystem. This is a post-14.0 activity either way.
