That's arguably the reason most popular CMS systems run PHP too; because they'd rather have something that's easier to setup and can be run nearly anywhere than something that requires knowing how to use a terminal or something.
I think shared hosting with php is mostly dead / makes no sense in a world of $5 VPS hosting.
Anyone caring for simplicity of installation would ship a Docker container anyway (for last 5 years or so).
It's a nightmare to maintain keep updated (manual processes galore), but it has a fast release cadence. The worst of both worlds.
I'm spoiled by Gitlab...
Just make that you have backups of your data, it's one thing to be deprived of services for x days, but a completely different thing to lose data forever.
I'm starting to work with minikube at work and I feel like that would be a fun solution for installation (well, minikube + helm).
Another solution that seemed cool but sort of puttered out was https://sandstorm.io
That said, it's a great platform. I have customers using it with some marketplace apps and some custom apps. My only wish is that more people used and developed for it.
I could have seen it be a great software dimension to home routers and NAS boxes.
Great for self hosting even on a single board computer or on traditional server hardware.
So don't judge too fast. Debian does a really good job now, even for desktop usage.
seeing how all the programs have evolved makes me so happy. there's a real alternative to commercial OS, at least for me :-)
