[Wiki] Verify if x86-64-v3 binaries are actually being used? #7

Closed GrabbenD closed 1 year ago

GrabbenD commented 1 year ago

I've installed Arch Linux via chroot by following instructions from: https://wiki.archlinux.org/title/installation_guide From there I added CachyOS repositories using steps from: https://wiki.cachyos.org/en/home/Repo After completing the installation, I figured most of the system binaries would have to be replaces with x86-64-v3 equivalents but it seems like that didn't happen (as this command completed almost instantly)?

Is there actually any way to make sure x86-64-v3 binaries from CachyOS repository are being used when installing from Arch?

@GrabbenD

  1. You need to place our repositories on top of arch ones
  2. You need to have our pacman installed
  3. You can check if package was installed from our repo with pacman -Qi ("Installed From:" section)

Thank you for the fast response @vnepogodin I followed your steps and Pacman recognized the new repos:

Just a follow-up question to make sure everything is correct, are some packages like linux not optimized for x86-64-v3?
