alt Hacker NewsI didn't really get into custom kernels until I started using Crux. A few years after I started using Arch I got sick of the rolling release and Arch's constant breakages, so I started looking into the alternatives, that brought me to Crux (which Arch was based off of) and Slackware (which was philosophically the opposite of Arch without sacrificing the base understanding of the OS). Crux would have probably won out over Slackware if it were not for the switch to 64bit, when confronted with having to recompile everything, I went with the path of least resistance. Crux is what taught me to compile a kernel, in my Arch days I was lucky when it came to hardware and only had to change a few things in the config which the Arch wiki guided me through.
Crux is a great distro for anyone ok with a source distro and I think it might be the best source distro, unlike the more common source distros, it does not do most of the work for you. Also love its influence from BSD, which came in very handy when I started to explore the BSDs and FreeBSD which is my fallback for when Patrick dies or steps back, Crux deserves more attention.
Arch always turned me off with it's rolling release schedule, and I wasn't that impressed with pacman to be honest. I used to love Slack, but they lost their way trying to compete with Ubuntu and the like. I remember thinking how ridiculous it was for mplayer to have samba as a dependency, and the community saying a full install was the intended way to run Slack. I ran it as a minimalist without issues until they started wanting to compete in the desktop space.
The best successor I've found is Alpine. It's minimal and secure by design, has an excellent package manager (I much prefer apk to pacman or xbps, or apt and rpm for that matter), has stable and LTS releases while letting people who want to be rolling release do so by running edge. People think it's only for containers but it has every desktop package anyone would need, all up to date and well maintained. Their wiki isn't at Arch's level, but it's pretty damn good in its own right.
