That’s true, but the biggest problem with their one-click install is that it doesn’t tell people that they should
cd /var/discourse
./discourse-setup
If you do that, it’s pretty much a Standard Install. (And if you don’t, you don’t get swap enabled, which will cause problems for 1 & 2GB Droplets, among other problems.)
This problem is really about the difficulty of moving from one host to another when you have https on, and that you can’t run let’s encrypt if the DNS doesn’t point to the new server. The “simple” solution is to rsync over /var/discourse, but that involves a handful of tiny little things that can go wrong.
