Log:
[USETUP]
- Remove some unused structure members.
- Consistently use the vocable "system partition" and "boot partition"
(using MS aka. hardware-oriented definition) according to:
https://en.wikipedia.org/wiki/System_partition_and_boot_partition
http://homepage.ntlworld.com/jonathan.deboynepollard/FGA/boot-and-system-vo…
in few words:
"system partition": the one that will be started by the platform firmware, and
where the bootloader is found (only one per computer);
"boot partition": the one where the OS of your choice resides (any number).
