Sorry for this rather ill-defined bug report, but I'm hoping someone will recognize the symptoms or at least suggest a way to debug this.
Ever since Fedora 33 was released we've been unable to produce a working virt-builder template. The template that we have made fails at switch root.
template: https://builder.libguestfs.org/fedora-33.xz bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1911177
An additional problem is I cannot find any way to debug the problem.
I would probably suggest to run an interactive anaconda install that reasonably closely matches the options you desire. This should give a working installed image that contains a corresponding working /root/install.ks file.
Compare that to the ks virt-builder is using and bisect the differences.
Something (systemd? dracut?) asks for a root password in order to get to the emergency shell, and I can find no way around this nor any password which works. I wish there was a "stop asking for a password" option on the kernel command line.
We use the same process to make these as we have always used, this kickstart:

Have you tried removing the whole of the %post script there ? The main ks rules that all look sane enough. It feels like that dracut invokation in %post is most likely thing to be causing a problem. Or perhaps the args to the 'bootloader' statement need an change in some manner ?
