Where can I find the source code of Voidlinux

# Why do I need to know where is the code source? I found a **_bug_** in the **config** file of the service named wpa_supplicant, when using some shell, like sh or zsh instead of bash for the root user

$ cat /etc/passwd

root:x:0:0:root:/root:/bin/zsh

this error is in this file : /etc/sv/wpa_supplicant/auto - Because in bash, we can find in two directories like that

for f in /etc/wpa_supplicant/wpa_supplicant-*.conf /etc/wpa_supplicant-*.conf ; 
do 
   #....
done

but we can't do it in another shell - my PR is changing this for-loop or adding bash shebang, ***but can't find `Void-Linux source in GitHub***
