Talk:Bug reporting guidelines
Recommend reporting bugs for Arch projects in their respective issue trackers
Bug reporting guidelines#Upstream or Arch? says that Arch Linux is responsible for "Arch Linux Projects: pacman, AUR, mkinitcpio, Arch Websites".
IMHO, people should be directed to report bugs in the respective project's issue tracker on gitlab.archlinux.org or GitHub (as linked in Getting involved#Software projects), instead of bugs.archlinux.org, if possible.
