Just cause you’ve never seen them doesn’t make it not true.
Try using quadlet and a .container file on current Debian stable. It doesn’t work. Architecture changed, quadlet is now recommended.
Try setting device permissions in the container after updating to Debian testing. Also doesn’t work the same way. Architecture changed.
Redhat hasn’t ruined it yet, but Ansible should provide a pretty good idea of the potential trajectory.
It isn’t. It’s architecture changes pretty significantly with each version, which is annoying when you need it to be stable. It’s also dominated by Redhat, which is a legit concern since they’ll likely start paywalling capabilities eventually.
Every complaint here is PEBKAC.
It’s a legit argument that Docker has a stable architecture while podman is still evolving, but that’s how software do. I haven’t seen anything that isn’t backward compatible, or very strongly deprecated with notice.
Complaining about selinux in 2024? Setenforce 0, audit2allow, and get on with it.
Docker doing that while selinux is enforcing is an actual bad thing that you don’t want.
So… you’re afraid of the command that does the thing you’re trying to do?
I’m surprised no one’s mentioned the security implications. Mounting with nosuid and nodev options can undermine rootkit or privileged escalation exploits.
Flatpak is itself a file manager.
That duplicate of your folder in /run is due to filesystem links (or more likely a fuse mount, I’ve never actually looked into how flatpak works). But either way, they aren’t copies of the data.
Don’t “declutter” manually. Use your package manager.
You’re going to want to look up things like symlinks, hard links, fuse filesystems, and bind mounts among other concepts. Your “whole directory” and other duplicates are artifacts of how the filesystem and process management works, and simply running fsearch or find over them is going to be confusing if you don’t know what you’re looking at.
One Unix concept that carries over to Linux is that everything is a file. Your shared memory space, process data, device driver interfaces, etc, all of it is accessible somewhere in the same virtual filesystem tree as the actual files.
Because of this, there’s very little reason to have the whole filesystem indexed from root. If you’re worried about space usage, you want to work with packages through the package manager. If you’re worried about system integrity, you’ll want package validators.
The above is accurate, and can be considered accurate for any directory below or at well.
Per /run, it’s also mounted in memory, so trying to “declutter” it won’t get you anywhere and things will return on reboot.
The focus on sales and deals and shit has been an attempt to compete with first Walmart and target, and then Amazon.
Used to be that department stores were where you went when you needed stuff. At one point, it was just where you went shopping for your general life. They tended to lower prices than boutiques through volume and you’d go to more specific, more expensive stores for more specific things.
Today, yeah. Why bother? You actually can find better clothes at Macy’s and Penny’s than Walmart, but you have to dig, and realize that the real Levi 501s are going to be $30 more than the modern Levi stretch fit trash. (And $30 less than buying them at the Levi store.)

Function/class/variables are bricks, you stack those bricks together and you are a programmer.
I just hired a team to work on a bunch of Power platform stuff, and this “low/no-code” SaaS platform paradigm has made the mentality almost literal.

Yup. Treating VMs similar to containers. The alternative, older-school method is cold snapshots of the VM, apply patches/updates (after pre-prod testing & validation), usually in an A/B or red/green phased rollout, and roll back snaps when things go tits up.

If you are in a position to ask this question, it means you have no actual uptime requirements, and the question is largely irrelevant. However, in the “real” world where seconds of downtime matter:
Things not changing means less maintenance, and nothing will break compatibility all of the sudden.
This is a bit of a misconception. You have just as many maintenance cycles (e.g. “Patch Tuesdays”) because packages constantly need security updates. What it actually means is fewer, better documented changes with maintenance cycles. This makes it easier and faster to determine what’s likely to break before you even enter your testing cycle.
Less chance to break.*
Sort of. Security changes frequently break running software, especially 3rd party software that just happened to need a certain security flaw or out-of-date library to function. The world has got much better about this, but it’s still a huge headache.
Services are up to date anyway, since they are usually containerized (e.g. Docker).
Assuming that the containerized software doesn’t need maintenance is a great way to run broken, insecure containers. Containerization helps to limit attack surfaces and outage impacts, but it isn’t inherently more secure. The biggest benefit of containerization is the abstraction of software maintenance from OS maintenance. It’s a lot of what makes Dev(Sec)Ops really valuable.
Edit since it’s on my mind: Containers are great, but amateurs always seem to forget they’re all sharing the host kernel. One container causing a kernel panic, or hosing misconfigured SHM settings can take down the entire host. Virtual machines are much, much safer in this regard, but have their own downsides.
And, for Debian especially, there’s one of the biggest availability of services and documentation, since it’s THE server OS.
No it isn’t. THE server OS is the one that fits your specific use-case best. For us self-hosted types, sure, we use Debian a lot. Maybe. For critical software applications, organizations want a vendor so support them, if for no other reason than to offload liability when something goes wrong.
It is running only rarely. Most of the time, the device is powered off. I only power it on a few times per month when I want to print something.
This isn’t a server. It’s a printing appliance. You’re going to have a similar experience of needing updates with every power-on, but with CoreOS, you’re going to have many more updates. When something breaks, you’re going to have a much longer list of things to track down as the culprit.
And, last but not least, I’ve lost my password.
JFC uptime and stability isn’t your problem. You also very probably don’t need to wipe the OS to recover a password.
My Raspberry Pi on the other hand is only used as print server, running Octoprint for my 3D-printer. I have installed Octoprint there in the form of Octopi, which is a Raspian fork distro where Octoprint is pre-installed, which is the recommended way.
That is the answer to your question. You’re running this RPi as a “server” for your 3d printing. If you want your printing to work reliably, then do what Octoprint recommends.
What it sounds like is you’re curious about CoreOS and how to run other distributions. Since breakage is basically a minor inconvenience for you, have at it. Unstable distros are great learning experiences and will keep you up to date on modern software better than “safer” things like Debian Stable. Once you get it doing what you want, it’ll usually keep doing that. Until it doesn’t, and then learning how to fix it is another great way to get smarter about running computers.
E: Reformatting
I actually want to learn enough code to contribute, but there’s this gap between “how to code” and “how to participate in a modern software project”.
Like, I’ve created plenty of little things. Discord bots, automation scripts, plenty of sysadmin stuff for work, etc. But like, I clone a git repo cause there’s a home assistant bug I’d like to fix for example, and I’m immediately lost on where to start.
Yeah, just make sure you don’t make that known during jury selection or you won’t get to help.
I think the thing in this case is that it is the job of police to pull over a box truck full of human cargo. The implication here is so you think they’d have let a truck they knew was full of immigrants just drive away?
The answer to your overarching question is not “common maintenance procedures”, but “change management processes”
When things change, things can break. Immutable OSes and declarative configuration notwithstanding.
OS and Configuration drift only actually matter if you’ve got a documented baseline. That’s what your declaratives can solve. However they don’t help when you’re tinkering in a home server and drifting your declaratives.
This right here is the attitude that’s going to undermine everything you’re asking. There’s nothing about containers that is inherently “safer” than running native OS packages or even building your own. Containerization is about scalability and repeatability, not availability or reliability. It’s still up to you to monitor changelogs and determine exactly what is going to break when you pull the latest docker image. That’s no different than a native package.
