community VS kiss-xorg

The Kiss Linux repos are not outdated, just the "official" one, there is one that is actively maintained by the community.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.

What was the problem with the XOrg repo? You should be able to clone https://github.com/ehawkvu/kiss-xorg.git and put it before other repos in your KISS_PATH. To run both Wayland and XOrg, you'll need to modify some packages such as mesa to build all the drivers necessary, and you'll need to enable xwayland in your compositor.

This repo is mostly outdated since KISS switched to Wayland. So you can either use Sway which is an i3 clone and in the official repos or, if you insist on using Xorg and i3, you can try adding https://github.com/ehawkvu/kiss-xorg. You will need at least xorg-server, xf86-input-libinput and something like xinit/sx/startx from there.

Do you use xorg ? Officially, only wayland is supported with Kiss. But there is an inofficial repo with xorg support. So only wayland, you must use wayland native softwares, xwayland is not available. But you can switch to the xorg repo.
