Currently there is no swap enable.
This leads to constraints when applications allocate a lot of memory and the overall memory is on the lower end with 4 GB and let's in the worst cause the OOM killer stopping the memory allocating process.
Like it currently happens with Teamred Miner in multiple GPU setup with only 4 GB system memory.

We should enable swap backed by a zram drive covering the full memory capacity or 8 GB whichever is smaller.
Similiar to how it was done successfully for Fedora 34.
