I've found out that if I specify /dev/sda like this:

$ qemu-system-x86_64 -hda alan_restore.img
-kernel /vmlinuz
-initrd /initrd.img
-append "root=/dev/sda ro init=/bin/bash"

then it finds, checks, and mounts the root file system. However now it 
fails because it tries to mount /dev and /run on /root/dev and 
/root/run, rather than simply /dev and /run:
