With zram, I can just use zram-generator[0] and it does everything for me and I don't even need to set anything up, other than installing the systemd generator, which on some distros, it's installed by default.
Is there anything equivalent for zswap?
Otherwise, I'm not surprised most people are just using zram, even if sub-optimal.
