madaidans-insecurities.github.io VS bedrocklinux-userland

They make detailed arguments for their position, for example, https://madaidans-insecurities.github.io/

The people who maintain the Linux security is fine also make arguments, but those arguments are much less convincing, such as the frequently-made argument that the fact that Linux's source code is readily available at no cost to anyone who wants to search it for security holes means that Linux's security will tend to be better than the security of systems whose source code is held secret.

Recommend reading the Linux sections on https://madaidans-insecurities.github.io/

That's somewhat telling and can be used to "track" you, consider reading on non-Reddit privsec learning resources like Privacy Guides itself which you already know, PrivSec.Dev, madaidan's Insecurities and the like.

Considering the offer is legitimate (something I won't comment on), you shouldn't do most of these things, in my opinion. Don't mess with what'll be other people's phones. Sell them Pixels pre-installed with GrapheneOS and print papers with Auditor attestation instructions and maybe a few QR codes directing them to relevant documentation and privsec learning resources, such as the GrapheneOS documentation first and foremost, Privacy Guides, madaidan's Insecurities, PrivSec.dev, Seirdy's Home, Wonderfall's Lab, etc...

i never used it myself. only learned about it from security experts like madaidan or hardening guides like this one.

For some excellent advice on security and privacy based on thoroughly researched technical concerns rather than speculation or blind trust in your corporation of choice, see here: https://madaidans-insecurities.github.io/

Back when I used a debian based distribution I made use of https://bedrocklinux.org/ to make use of the AUR. It's not for everyone though.

Now this is interesting... apparently it is possible to run Nix AKA "The Nix Package Manager" on Alpine -- despite the fact that Alpine is Busybox and Musl based and NixOS is Coreutils and Glibc based!

Well done Nix engineers and contributors!

(I may switch to Alpine w/Nix Package Manager in the future, depending on how well it works!)

Bedrock Linux: https://bedrocklinux.org/

Sure, just install Bedrock Linux and add the Arch stratum on top

There's a Bedrock Linux distro already...

Bedrock Linux. It is allows you to make a system out of various seemingly-incompatible parts of other distros. I haven't gotten around to trying it myself, but it's really cool.

If you want to actually use multiple distributions at once integrated tightly into each other (like using Ubuntu with AUR packages) I highly recommend https://bedrocklinux.org/. It uses some chroot and symbolic link magic to share files across filesystems.
