mkinitcpio VS svntogit-packages

This file has been changed recently and the wiki still references the old line. You have to modify this line now:

mkinitcpio is an arch thing: https://github.com/archlinux/mkinitcpio

The Arch Linux devs don't have infinite time and energy, so yes less-important issues that affect less users get diprioritized. You're welcome to PR the fix yourself, here's the mkinitcpio repo: https://github.com/archlinux/mkinitcpio

The general logic was changed in the new mkinitcpio release. https://github.com/archlinux/mkinitcpio/pull/54/files

That's an odd one since reinstalling the package fixes the issue. I wouldn't be so sure it's grub because it just loads the vmlinuz and initramfs that are suffixed with the pkgbase. That will not change based on the kernel version and pkgrel version. Someone brought up needing a hook. the mkinitcpio package already installs hooks and scripts necessary for maintaining a mkinitcpio prefix for each kernel for the initramfs image generation and installing vmlinuz to /boot/vmlinuz-${pkgbase} on upgrades. Everyone with the official mkinitcpio package is going to have the same /usr/share/libalpm/scripts/mkinitcpio-install shell script. Running grub-mkconfig is pointless for a kernel upgrade for the reason stated. All it does is export variables from /etc/default/grub and concatenates /etc/grub.d/* into a single config file. If there was a grub config issue it's unlikely you would ever be able to boot.

mkinitcpio made zstd the default on 2021-02-17

The number of thread is, but the compression level isn't. Because -3 is a sane default for the compression level in time of compression time and output file size, but this can differ for your machine. I find that on my machine best compression level is -15 or -16 for size and compression time. Since it will take a 1 second more to compress but it will yield a file 80% more compressed than the default. Here is the pill request where the defaults where changed mkinitcpio#47

More sanely, just makepkg the official pkgbuild from archlinux extra.

Packagekit support has been dropped from the gnome-software package https://github.com/archlinux/svntogit-packages/commit/d62208b27b99de982318d58d87a9125def07f626

git clone https://github.com/archlinux/svntogit-packages.git --branch packages/$pkgname --single-branch $pkgname

For example Arch applies quite a few patches to Chromium.

Yep looks like ffmpeg package needs to be rebuilt against svt-av1 1.5.0. In the meantime you can checkout, build & re-install the ffmpeg pkgbuild locally to fix.

Download the PKGBUILDs from the archlinux svntogit trunk and use makepkg as you'd normally would I guess. Here's the PKGBUILD for gnome-shell v. 3.38.4 for example: https://github.com/archlinux/svntogit-packages/blob/e93ee10b663dedcebfd8c33fd53b82f642a0a0a8/trunk/PKGBUILD

The old python PKGBUILD from the Arch repos is here, in case anyone wants to build it themselves under the python310 name (with additional minor modifications): https://github.com/archlinux/svntogit-packages/blob/855d73921bb8e86820a7731870de335c3c2fa236/trunk/PKGBUILD
