wyverkiss VS community

Clang by default is also quite interesting. Apparently, you can replace most of the GNU toolchain with an LLVM-based toolchain. Wyverkiss Linux implements this in their distro. I believe it's an interesting way of fully achieving a GNU-less system (if you'd like to do that).

Initially it was this project - from there I wanted to see how much further I could take it.

The Kiss Linux repos are not outdated, just the "official" one, there is one that is actively maintained by the community. https://github.com/kiss-community/community.

Yes. The init scripts are written so as to be as init-agnostic as possible. See here to see what has specifically been tested. You'll need to either change what owns /sbin/init or, when configuring the kernel, change what executable it spawns as PID 1. Depending on what init you use, you may have to set up a service manager or gettys manually like this -- custom scripts are placed in /etc/rc.d with self-explanatory suffixes .boot, .pre.shutdown, or .post.shutdown.

back is packaged in the community repository: https://github.com/kiss-community/community

If you use the Official unofficial community repository, watch out for packages that might get dropped by maintainers.

Again, if you had bothered to read the sidebar you would have seen links to both the community site as well as the community github repo.

I am very exited for https://kisscommunity.org, the possibilities are endless!

Kiss linux is what you are searching for

This might not be exactly what you are looking for but KISS linux (https://k1sslinux.org) is a distribution that doesn't force ANY init on you, supports disk encryption ofc, it's probably the most light and minimal distribution out there (the core install has 7 packages), it's rolling release.
