I didn't even know what it is -- but the zram(8) man page and a little
guesswork at least leads in some direction.

I assume you'd want to load the zram kernel module (sudo modprobe zram,
I'd guess) to be in in the fun.

There's some doc about the Linux kernel module itself (just follow the
link in the above man page).

Let us know how it works out and... make a backup first!

Cheers
