@lain just install your basic apps. I promise you installing chromium via pacman or flathub or dnf or apt is way easier then trying to troubleshoot endless bash scripts.
If you really really want a shit ton of installed software then just use opensuse. That iso is heavyy.
Some of this is personal opinion since I definitely prefer slightly lighter installs on all os since I prefer to install the software I want so I can make sure it’s the right package format, version etc, but after seeing how omoarchy I just can’t in good faith recommend it to anyone. Like just use cachyos if you want easy configuration arch hyprland because atleast that team doesn’t ship every new release with sever input validation bugs in vibe coded bash.
