I recently took up Bazzite from mint and I love it! After using it for a few days I found out it was an immutable distro, after looking into what that is I thought it was a great idea. I love the idea of getting a fresh image for every update, I think for businesses/ less tech savvy people it adds another layer of protection from self harm because you can't mess with the root without extra steps.
For anyone who isn't familiar with immutable distros I attached a picture of mutable vs immutable, I don't want to describe it because I am still learning.
My question is: what does the community think of it?
Do the downsides outweigh the benefits or vice versa?
Could this help Linux reach more mainstream audiences?
Any other input would be appreciated!
That doesn't make it not immutable. /bin is not a critical directory in NixOS, only the contents of /nix are, which are immutable. /bin isn't even part of your path by default.
Well that was an approximation to keep it simple and disprove the given example. There are other directories in the root filesystem that are in the path by default, or used in some other critical way (like
/etc). Even if they are links to directories in the nix store you can replace the link.I understand, but it didn't really disprove anything. Immutable distro's protect core components from being modified. /bin is hardly relevant on NixOS, so of course it wouldn't be made immutable.
/etcis also generally not considered a core component, and every immutable distro I've used left it writable. By default, every binary installed through NixOS is put in/run/current-system/sw/bin, which is immutable. Many other important files are also linked to/run/current-system, which is why the whole directory is immutable. It essentially takes the place of what the root directories would be on an FHS distro.I don't know any other path used in critical ways that is not immutable. The primary paths that immutablility is relevant for in FHS distros are /usr, /lib, /lib64, and /bin. None of these paths are really used on NixOS, besides some files symlinked there for edge cases, like /bin/sh.
If you were to remove all the symlinks you are able to, the system would still work for the most part. You would lose custom configurations in /etc, but that is true for most immutable distros. Most apps have a default configuration to fallback to.
The misunderstanding comes from the fact that immutable is a poor description for any OS, which is why many now use atomic instead. Even in immutable distros, many files can still be modified, and things can still be broken if you try hard enough. Still, NixOS definitely falls under the general description of and immutable distro, as the core of the OS is immutable.
