Also, from what I understand, they accept Monero for their laptops.

That’s very cool. I didn’t even know that. Thank you for mentioning that!

These changes are undocumented and must be discovered and explored organically, while the default behavior is well documented.

This, indeed, is concerning. Thank you for mentioning this!

Kickstart.nvim ads only a few packages that are very popular and provides a base upon which you can customize as needed.

Hmm…, allow me to ask the following: How much effort would it take to get Kickstart.nvim from scratch to where any of the opinionated distros are in terms of functionality?

I like Spacevim a lot

Have you tried any of the ones mentioned in the OP? If so, would you be so kind to elaborate upon why you prefer SpaceVim over the others?

(inspired by SpacEmacs)

Interesting. Would you be so kind to elaborate on what this entails?

you can use neovim as the underlying vim package as well. Then update init.toml with whatever layers/plugins you want

That seems kinda hella streamlined and straightforward, which is honestly pretty cool. Is this different from how it works on any of the ‘(Neo)Vim distros’ and/or by default?

It seems to offer a leaner approach. If you’ve used any of the ones mentioned in the OP, would you consider offering a more elaborate comparison between them?

I’ll assume that you intend to use it as a traditional daily driver, as such Tails and Whonix will not be taken into consideration. Qubes OS will also be dismissed as it’s technically not a Linux distro. Though, it’s simply the best if you take security seriously.

Within the space of traditional Linux distros, the closest one would probably be Kicksecure. Madaidan even works on the distro, so I’d say it’s fair to assume that it upholds some of the values that are mentioned in the article.

Alternatively, packages for Fedora that would set this up automatically

Hehe, wishful thinking 😂. Uhmm…, bummer, but such a thing simply does not exist. Best we’ve got would be relying on so-called hardening scripts made by people that you don’t know but somehow trust for hardening your system. Honestly, I’m also -to a degree- guilty of this as I one day hope to either adopt these scripts or rebase to one of these hardened ‘immutable’ Fedora images (when they’re ready); Madaidan’s guidelines have actually been an initial inspiration for the scripts found in the first link, so yeah 🙂. Until then, our best bet would probably be relying on hardening guides like this one; the guide has been carefully written (and is still getting regularly updated) with consideration for all the different major distros one might be using. Alternatively, you might try to implement Madaidan’s guidelines directly. But, my previous attempts on Fedora didn’t bear the best results. Though your mileage may vary. Special shout out to Brace as it’s the closest thing to a package that does the hardening for you and works on multiple distros including Fedora. It’s maintained by the same people that have brought us the excellent DivestOS, so it’s trustworthy.
