Yup.   For example, imaging an initrd that loads up, insmods some closed source
kernel modules needed to mount the real root filesystem (i.e. the m-systems
disk on chip driver).  For this you can just compile up busybox as a standalone
shell with insmod, and have your /linuxrc be a shell script that just runs:

    #!/bin/busybox sh
    insmod foo
    insmod bar

No busybox symlinks needed, just a few /dev entries and a statically linked
busybox.
