ports VS fmoad-cailin

I think OpenBSD comes the closest to what you want with its two easy to use syscalls that provide syscall filtering and restricting access to paths:

https://man.openbsd.org/pledge.2

https://man.openbsd.org/unveil.2

A few random examples:

https://github.com/tmux/tmux/blob/c8494dff7b6b9a996866edaf8c...

https://github.com/openbsd/ports/blob/master/www/mozilla-fir...

https://github.com/openbsd/ports/blob/master/www/mozilla-fir...

To get the best isolation you need to patch the source — the application needs to go through initial setup and then drop privileges to the absolute possible minimum. But it's easy to make custom wrappers for third-party applications — the above profiles taken from the OpenBSD ports tree are the proof.

Have you checked the no-ip port: https://github.com/openbsd/ports/blob/master/net/no-ip/pkg/noip2.rc

> https://github.com/openbsd/ports/commit/bf33ea5f3ff390d8cde3...

Now, this is surprising. I randomly clicked on that link and I immediately see that the code and the patch has a bug. It only checks the first 8 characters:

    -      if (gr != NULL && strncmp(gr->gr_name, "operator", 8) == 0)

Some people are working around this by using obsdfreqd, some by patching sys/kern/sched_bsd.c (change if (hw_power) to if (0 && hw_power)), some by simply setting to a lower speed (sysctl hw.perfpolicy=manual and hw.setperf=99 might be enough as this disables turbo mode found on some CPUs).

You could also look into a port that has a hard dependency on openssl like: https://github.com/openbsd/ports/tree/master/security/sslscan

For me it's the ease of management and good documentation.

For example, during 6.8 to 6.9 upgrade, there was a major postgresql upgrade.

It is mentioned in the doc https://www.openbsd.org/faq/upgrade69.html (see Special packages at the bottom).

You're redirected to the package README with special instructions on how to setup and upgrade: https://github.com/openbsd/ports/blob/master/databases/postg...

Et voilà, everything is explained.

On debian, if I am not careful, I'll do an upgrade and risk breaking something during a db migration (I'm looking at you MySQL upgrades...).

Godot engine gamecontroller support. This is limited and incomplete, but it's a start. A huge number of indie games made with Godot are released every week; most of which work at least partially with an XBox {360,One} controller. You can follow This Week in Godot if you're interested.

> OpenBSD has handled this case for some years. I do not know if there was any breakage or fallout from this.

The other thing about OpenBSD is that when they make a change to their OS, they also go through to make sure all the (third-party) ports/packages:

* https://cvsweb.openbsd.org/ports/

* https://github.com/openbsd/ports

do not break. So they're create patches for the software and and submit them upstream.

The OpenAL-based implementation of FMOD is stuck, due to 1) I can't so far figure out how to fix the music restarting with every scene switch in Celeste, and 2) there is so far no solution to easily get the ID of the music tracks.

This is a look at what I've worked on. The setup is still a bit of a hassle - details are in the GitHub/CVSWeb repo README file. I have some thoughts on how to reduce the setup hassle if this should get more traction.
