I understand how, once it has grub.cfg, it decides what to boot. It's
where grub.cfg comes from that I don't understand.
Pretty sure at that stage it has loaded modules that let it interpret a
selection of filesystem types, in order to fetch grub.cfg (and further
grub modules). Therefore you need grub modules for whatever filesystem
types (and similar) are needed to get to /boot; historically, that
excluded md (and lvm) and so /boot was typically not put inside LVM or
md RAID — more recently I believe GRUB can interpret LVM and MD devices.
