The tmpfs filesystem is backed by anonymous memory, which means it can be swapped out at any time, if there is memory pressure [1]. For this reason, a zram swap device is a much better choice than mounting /tmp on zram, since it's able to compress all anonymous memory, and not just the memory assigned to /tmp. We already have the zram-swap package for this specific purpose, which means procd's tmp-on-zram is both redundant and more limited. A follow-up patch will remove support for mounting /tmp in zram from procd itself.
