/etc/resolv /etc/interfaces, netstat, ifconfig (hey!, I prefer "i a s" over ifconfig though ) ... not working properly and as its supossed ten years now, and 90% google says... is wrong now
Every distro linux has his way to manage network. Last bug in Kde Neon I was using about proxy configuration (https://bugs.kde.org/show_bug.cgi?id=410843) took me two hours to fix.
So I'm going to try BSD or something without systemd.
Sure I'm tired and old but I don't see advantages win over the problems can occur. It's a mess for me now...
I like the most updated applications, libreoffice,bash ...and love shortcuts with keybindings
for which distro I look?
Arch Linux provides awesome documentation though. Slackware still follows the old ways iirc.
For *BSD, I'd personally stick with OpenBSD, but not sure how great you can expect it to be as a distro.
Be aware that it is a rolling release distro, much like Arch Linux and it comes with its drawbacks as well. It uses runit as its init system, which is easily configured via shell scripts, and certainly won't change in the near future, because it's feature complete.
Void comes with it's own package manager, "xbps" (X binary package system), which is used a lot like pacman on Arch Linux. You can even freeze packages if you don't want to upgrade them.
All in all, I'd recommend it, but be sure to play around with it for a bit before settling on it. (Oh, and the installer is a lot easier thatn Arch's too, and there are live CDs with desktop environments pre-installed if that's your thing)
