If dracut is used to generate the initrd, then /sbin/init is a symlink to /lib/systemd/systemd. I suppose your comment only applies if initramfs-tools is used in lieu of dracut.</p>

For removable media FAT12 and FAT16 are required to be supported by the firmware. At least Fedora creates ESPs with FAT16 (on non-removable media). And EFI macs don't boot from the FAT32 ESP, instead the firmware has read support for HFS+ and APFS, and reads the bootloader from one of those file systems.</p>
