Adding dracut-config-generic to the kickstart package list should have the same effect (not tested though). That'll disable the root login in the initramfs and sulogin gives you a shell when you tap enter.

Weirdly it works when I comment out the dnf update: %post # Ensure the installation is up-to-date. -dnf -y --best upgrade +#dnf -y --best upgrade which I certainly wasn't expecting.

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.

[3.174123] systemd[1]: initrd-switch-root.service: Main process exited, code=exited, status=1/FAILURE [3.176615] systemd[1]: initrd-switch-root.service: Failed with result 'exit-code'. [3.179342] systemd[1]: Failed to start Switch Root. [FAILED] Failed to start Switch Root. I wonder what causes it to say that? The disk image itself has /etc/os-release -> ../usr/lib/os-release and /usr/lib/os-release is a regular file. The symlink ought to work since it is a relative path. The kernel finds the virtio disk so it has at least the block drivers. > > 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 suppose vda1 must have something to do with UEFI. Thanks anyway, this gets us a little bit further.

Fedora 33 virt-install + ks has some problem switching root
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. 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: https://github.com/libguestfs/libguestfs/blob/master/builder/templates/fedora-33.ks is fed to this virt-install script: https://github.com/libguestfs/libguestfs/blob/master/builder/templates/fedora-33.virt-install-cmd and the result is minimized. (I tried turning off the minimization steps, it seems the output of virt-install + ks is broken, not anything we do afterwards).
