CUPS isn't necessary to print, either. It is a convenient solution,
but others exist.

Possibly. Other print solutions exist.

Exactly. OTOH, trying to make everything work with every possible print
driver is not necessarily a good goal.

I suppose a "minimal required system" would be the kernel, the init
RAM disc, and tmpfs for /tmp. Not a very usable system. But when
you go beyond this, then you get into "minimal required to do <x>"
where <x> is some desired function. Everyone seems to have a different
set of <x> to put into there. I don't know of any objective means
to ascertain what <x> must contain.

I was amazed when I installed FC2. I didn't think I selected
all that much to install. It was about 7 Gig.

All systems seem enormously bloated to me these days. But I
started with computers when 4K of RAM was considered a lot.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
