Kernel parameter root= appears to be missing. Unless you know for absolutely certain that the early userspace is capable to figure out the root partition on its own, you'd rather put it into your bootloader's config.
Thanks but I don't have any bootloader config nor need any[1]. The parameter should handle anything initramfs needs -append 'root=r rw rootfstype=9p rootflags=trans=virtio console=ttyS0' In my opinion with `root=r` it defines root, where `r` is the mount_tag: ` -virtfs local,id=r,path=/root/arch,security_model=passthrough,mount_tag=r,' the mountpoint is /root/arch (on the hostsystem) On the recovery shell I can type mount -t 9p -o trans=virtio r new_root/ and `r` does exactly what I want, it mounts `r` which is /root/arch on the host system to the `new_root` directory as a VirtFs Filesystem. So I don't know why I does not find `r` by itself: ERROR: device 'r' not found. Skipping fsck. ERROR: Unable to find root device 'r'. Do I have to 'swap' anything in here?
