The idea was to copy (not move) booting software to /sbin instead of an initramfs - the exact same programs, modulo noise - to have the SW in /sbin necessary to mount /usr. Our loveable upstream suppliers are making us mount /usr early in the boot process. Why can't this be done as well from /sbin as from initramfs?
