Just using the example of "df -h" and "mount" ... all the extra stuff that wasn't there 15 years ago, is from systemd. The idea is to auto-enable anything anyone might possibly want, to whatever extent possible, and I don't like it. I also noticed the /var/credentials/ mounts showing up recently; that's for a systemd feature that neither I nor you actually use, to set encrypted secrets for these services in a way that is exposed only to those services via a centralized framework. If you didn't explicitly use it, it's all empty. But it started years ago with the mounts for efivars, pstore, binfmt-misc, kernel/debug, kernel/security, etc. Sure they're useful sometimes, but they shouldn't be enabled until you have a need and then explicitly enable it. Well, that's my preference, so I always start with minimal debian or arch linux, but even on such minimal systems that have switched to systemd, you get all this stuff enabled and mounted by default. If you're actually using a tmpfs mount, like perhaps just one on /tmp, then you do want df to tell you how full it is. The problem is that you have 20 fs mounts that are truly useless to you, and IMHO should not be there. And ironically I think systemd developers do have a strong opinionated design vision, and if you don't like it you can pound sand (or use void or alpine for a desktop system I guess), because they have successfully taken over the vast majority of the desktop and server linux ecosystem. Anyway I still like linux for the flexibility I have elsewhere in the stack to make it work the way I want, reasonably conveniently for me. (Many would think I'm an idiot for not appreciating the brilliance and necessity of what systemd has done, but for a completely different angle about systemd I recommend: https://blog.darknedgy.net/technology/2020/05/02/0/ https://blog.darknedgy.net/technology/2020/05/02/0/ (seems tls cert expired a few days ago, but it's fine to ignore))
