Asking the system to mount anything at / doesn't make much sense, because
the fact that systemd is running and can read its unit files already means
the rootfs is mounted... (There's always something mounted at /; if it's
not the real rootfs, then it's the initramfs or something.)

If you're just trying to *re*mount / with different options, that's not
done via .mount units – it's done by systemd-remount-fs, which always
parses the fstab. But in that case, why not specify the correct mount
options in the first place? Putting "rootflags=discard,noatime" in the
kernel command line should be enough.
