- Add locate group to group file
- Export PKG_CONFIG_PATH in /etc/profile
- Add /etc/modprobe.d/usb-load-ehci-first to address #12009 (the latter
needs a small change in mkinitcpio, so this file will also be added to
the initramfs, this will fix the issue for people who use the usb and
usbinput hooks, I'll do that tonight).
