popularity doesn't necessarily dictate whether or not something is better.
Archlinux or voidlinux?
Void is pretty cool,trips-user.
The only complaint I have is that the documentation on XBPS isn't as comprehensive as I would have liked.But that isn't really anything unexpected.
Artix: Arch - Systemdick
If you don't need any of the packages that Void lacks (like OpenJDK 8) then go with Void. Otherwise Artix, which just werks and has everything.
This.
are the only differences the init system(s)? does everything else come directly from the arch repos or their own?
Most comes from the Arch repos. What depends on systemd is on their own repos, without systemd.
(checked)
Void is very simple and the default installation is very small, that's why I pick it as a default distribution to install on new machines. A year or two ago I had issues with the lack of packages in the repository and package naming (mostly during compilation from source) but since then all the packages I couldn't find have been added and I just got used to the naming conventions (though they still kinda suck). One problem, however, is that it's clearly an amateur project. The forum is dead and the wiki is pretty poor. I doubt Void will last for long.
Do you dare enter the void?
Or are you a straight up man child who thinks cutting edge means anything other than cutting yourself on some edgy packages.
Install Gentoo.
