If you run a server as a business, making sure that things keep working is the most important thing to have. That’s what most Linux distributions focus on: stability.
If you tested that your application works on, say, Debian 12, then you know that you will always be able to set it up on Debian 12 and it will keep working without issues. Because Debian 12 is Debian 12, it ships with the software and versions of software that Debian 12 shipped with, and that will not change. When it’s time to upgrade to Debian 13, you can test that your application works on Debian 13. And if it works, then you know it works.
Rolling release distros are highly unsuitable for this, because you never know when a package gets a big update that breaks other software. So businesses generally don’t want rolling release distros, and so hosting providers have little reason to offer them.
Almost.
Discourse has a setting that lets you configure how long people are logged in. By default, it was set to keep you logged in forever. But that creates a bit of a weird situation where you may be logged into the forum but not the client area. I disabled that setting now so Discourse uses regular session cookies instead of persistent cookies, which means that you’ll need to login a little bit more often.
But if you are logged into the client area with Remember Me enabled, then that should only be a single click on the Login button.
