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/fedor...
is fed to this virt-install script:
https://github.com/libguestfs/libguestfs/blob/master/builder/templates/fedor...
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).
Rich.
