If you need to learn about linux, read, young man. Google and read.

A rootfs id the hard disk install of your system. Until that disk is mounted there is only the kernel in memory. If that is short on kernel modules, there is an initrd or initramfs mounted on / which has what's missing. This vanishes when the rootfs is mounted on /
