What it sharing the partition with /home? And what is it's
mountpoint?

Which one is, usually?

In the previous post, we had "data array" aka "data repository",
SSDs for booting, and a NAS or file server (whose data repository
needs to be huge), plus a "single set of array spindles".

With that wide choice, I'm not clear what "targets" are, nor how
all these different items are arranged with respect to the PC
itself (or which are entirely separate entities).

What are the benefits of /boot on a RAID? Does that mean that a RAID
has to be assembled even before the PC can boot up?
