Ok, I booted with break=bottom, and no file system was mounted other than the 
nfs:

(initramfs) mount                                
rootfs on / type rootfs (rw)                     
none on /sys type sysfs (rw,nosuid,nodev,noexec) 
none on /proc type proc (rw,nosuid,nodev,noexec) 
udev on /dev type tmpfs (rw,size=10240k,mode=755)
192.168.53.66:/local/debian-live/binary/live on /root/live/image type nfs 
(ro,vers=3,rsize=524288,wsize=524288,namlen=255,hard,nointr,nolock,proto=tcp,timeo=7,retrans=3,sec=sys,mountproto=udp,addr=192.168.53.66)                                                  

I was able to manually mount the filesystem, but only after manually loading 
(ie. modprobe) the loop and squashfs modules:

(initramfs) mount -o loop /root/live/image/filesystem.squashfs /root
mount: cannot setup loop device: No such file or directory

(modprobe loop, modprobe squashfs)

(initramfs) mount -o loop /root/live/image/filesystem.squashfs /root/
(initramfs)

Any ideas why this didn't happen automatically?

Cheers,
Andrew
