No no, it's fine, no problem.

Yes it is. But there are lots of them. And me, personally, for
workstations, I avoid all of them. I use it, very judiciously, on
servers _only_. And then, generally not on boot drives.

That seems weird to me, but OK, whatever you like.

I don't know. I've only done full-disk encryption on Linux once,
because a previous job insisted on it. I thought it a tragic waste of
computer power and performance. I followed a cheat-sheet in order to
configure it, and even so, it took 2 or 3 tries to get it working. As
far as I remember, it required a password even before the GRUB menu
appeared, but it was over 2 years ago and I don't remember.

I used LUKS, incidentally.

Dear gods, no. As I said, I hate it and never use it unless mandated
by my employer. The same applies for LVM on workstations.

No. I have used it on a number of low-spec notebooks and a Raspberry
Pi 3 and it worked without any problems.

It's just a script that sets up swapping to a file in the root
filesystem. I've used it on a number of servers without any problem as
well.

That's what swapspace sets up for you.

Disclaimer: I have not used it since 14.04. I have used it
successfully on both 32-bit and 64-bit systems.
