There is a system-wide /etc/profile or /etc/profile.d/ Likewise, zsh will look for /etc/zshrc And zsh will actually look at $ZDOTDIR/.zshenv $ZDOTDIR/.zprofile $ZDOTDIR/.zshrc $ZDOTDIR/.zlogin $ZDOTDIR/.zlogout So perhaps you can set the value of ZDOTDIR in one of the systemwide locations to use "$HOME/foo/bar/zsh/" and this way zsh will use ~/foo/bar/zsh/ as the location for the user specific .zshrc and other mentioned files for every user https://eng.libretexts.org/Bookshelves/Computer_Science/Operating_Systems/Linux_-_The_Penguin_Marches_On_(McClanahan)/02%3A_User_Group_Administration/5.03%3A_System_Wide_User_Profiles/5.03.1%3A_System_Wide_User_Profiles%3A_etc-profile https://eng.libretexts.org/Bookshelves/Computer_Science/Oper... https://bash.cyberciti.biz/guide/Setting_system_wide_shell_options https://bash.cyberciti.biz/guide/Setting_system_wide_shell_o... https://zsh.sourceforge.io/Intro/intro_3.html https://zsh.sourceforge.io/Intro/intro_3.html
