yeah, leak all swapped data into their cloud shiver
-
You're right, we should add an encryption step as well!

Furiously sets up a LUKS swap partition on Google Drive

Will kind-of-work for users with gigabit+ links, actually.

It really doesn't ...the latency is sooo bad

That's why "kind-of-work".

I vaguely recall that Linux has support for multiple tiers of paging space, with you able to assign priority.

Yeah,
swaponhas a-pparameter`.https://linux.die.net/man/8/swapon
-p, --priority priority Specify the priority of the swap device. priority is a value between 0 and 32767. Higher numbers indicate higher priority. See swapon(2) for a full description of swap priorities. Add pri=value to the option field of /etc/fstab for use with swapon -a.So you shovel the priority below your local paging space, might be okay for some workloads.
I dunno if there's any system to predictively migrate data between tiers of paging space, though. If it only pulls into main memory from low-priority paging space and does so a page at a time, that's gonna be painful.
Also, this definitely increases the security risks associated with having sensitive material being paged out beyond the usual "someone might get your laptop and look at the paging space when it's off if the paging space isn't encrypted and you're using software that doesn't lock security-critical data in memory" stuff.

Not at all, it's way too slow.

this hurts my brain

My ISP: what a wonderful thing you have there. I will definitely not charge you an arm and a leg for the bandwidth
-
is that a whole petabyte of swap???
-
That's one way of making your temp memory even slower.
-
could the filesystem driver get evicted to swap?
-
Nope, it's always in memory (while module is loaded).

In case anyone is curious if this would work, LTT tried it: https://youtu.be/minxwFqinpw
Thanks! I hate watching a whole video for something that could be a paragraph at most.
Thank you! I was curious but not ten-minute-video curious. I wonder if there's a cloud provider that doesn't block this sort of usage - could it work with onedrive/dropbox/etc?
