rootfs is mounted by the kernel, not by kinit.  It's the only thing 
moved by the root.

udev is usually responsible for creating the /dev/root symlink for the 
full-fledged userspace.

By the way, this is not limited to klibc-using kernels.  Stock FC5 has, 
for example:

: tazenda 3 ; cat /proc/mounts
rootfs / rootfs rw 0 0
/dev/root / ext3 rw,data=ordered 0 0
