I started with some UMSDOS-based "full X11 desktop in 5 floppies" distro on a 486, then went through Slackware, RedHat 5 with glibc breakage, actually bought a SuSE boxed set in the 7.x era, mostly stuck with Slackware unril I realized I wanted stuff like Steam and perhaps some degree of dependency resolution is nice. Bounced off of Arch (the AUR is a terrible concept IMO) and ended up on Void, which gives me Slackware-like vibes, but a little more built for broadband instead of CD images. Been trying Debian Sid latrly, just because I put it on my new laptop and I figured I'd go consistent, but I'm not sure I'm sold. Everything works, but even for an "unstable", the packages are dated and I dislike systemd on principle.
I run Arch but don't install anything from the AUR unless absolutely necessary (or if it is dead simple enough for me to understand). I find the pacman-only experience makes a great stable low effort stable PC with all the latest bells and whistles. System updates on the weekend, once a week. No problems.
Interesting. It looks like there's a couple criteria to get something into the Extra repository, but the primary one looks to be a ready and willing package maintainer. Sounds like that hasn't happened yet for fvwm.
