Hi, Matthew.

When an RHEL (or any other Linux) boots, it starts up from a RAMdisk (see
/boot/initrd*), which contains enough of a filesystem grouping to boot the
system and perform initialization.

At a certain point, it goes ahead and mounts your actual root (/)
filesystem, at which point it spits out that message.
