I couldn’t agree more with this, projects like artix are undermined by all the hard dependencies on systemd and Bash.
Void attracted me because of the support for posix, runit and musl (plus good zfs support). It’s unfortunate that Arch doesn’t have that greater portability.
There are many advantages relative to bash, especially much better array handling, and comprehensive globbing and expansion expressions. You can reduce your reliance on external tools, which may have multiple alternative implementations (a source of unpredictability).
