What is the rationale of this patch?
Supporting systems without /etc/fstab in the root device?
Overriding the /etc/fstab settings?

In a systemd initrd (e.g. in dracut) as soon as initrd-root-fs.target is
reached, initrd-parse-etc.service is executed, which retriggers the
fstab-generator and reads fstab from the real root and generates units for /usr.
