Yes, I wondered about this. I even questioned the purpose of specifying
the root filesystem in fstab since it is already present as a kernel
parameter in GRUB.  Is this the flow of events?

- kernel mounts read-only the root filesystem specified as kernel
parameter in GRUB
- init/systemd reads fstab and remounts root-filesystem read-write
(along with specified mount options)

Thanks,
