For small instances how can I force ./discourse-setup to stop nagging about SWAP creation for a 1c2r vps?
You would need to modify the script to bypass the test. You could do that and it won’t work. The script requires swap because it won’t work without swap.
If you don’t want swap and you have less than 4gb of ram, you can’t have discourse.
This is true even for systems with 4G or Larger RAM allocation. Before discourse started bundling assets, there was always a chance that builds fail during compile due to OOM and Having a Large SWAP (4G in our case) was the only viable remedy.
Nowadays it goes smoother than that but still having a swap even on devices with large RAM allocation is still worth it.
this is re-assuring for someone like me, whom has Larger RAM allocation
