Interesting thanks - I can reproduce the error using your suggested
command line:

[    3.167930] systemctl[272]: Failed to switch root: Specified switch root path '/sysroot' does not seem to be an OS tree. os-release file is missing.
[    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.

AFAIK we don't do anything unusual.  We're using autopart --type=plain
in the kickstart which should make a non-LVM partition.  I suppose
vda1 must have something to do with UEFI.

Thanks anyway, this gets us a little bit further.
