With the release of mkinitcpio v38, several hooks previously provided by Arch packages have been moved to the mkinitcpio upstream project. The hooks are: systemd, udev, encrypt, sd-encrypt, lvm2 and mdadm_udev.
To ensure no breakage of users’ setup occurs, temporary conflicts have been introduced into the respective packages to prevent installing packages that are no longer compatible.
The following packages needs to be upgraded together:
- mkinitcpio 38-3
- systemd 255.4-2
- lvm2 2.03.23-3
- mdadm 4.3-2
- cryptsetup 2.7.0-3
Please note that the mkinitcpio flag --microcode, and the microcode option in the preset files, has been deprecated in favour of a new microcode hook. This also allows you to drop the microcode initrd lines from your boot configuration as they are now packed together with the main initramfs image.
So there’s two parts to this announcement. The first one deals with the upstreaming of modules and the resultant conflicts with the Arch packaged versions - this was solved by Arch upstream by introducing conflicts. In this case, you don’t need to do anything.
The second part is about the microcode loading, where the old method of loading the microcode is deprecated, in favor of the new method (ie making it part of your main initrd). Now it’s just deprecated, so you don’t have to take any action either, but if you don’t, you’ll see annoying warning messages from mkinitcpio, whenever your kernel/initrd gets updated. But eventually, the legacy option will go away, and you’ll be forced to take action. So might as well do it now, because Arch ain’t going to do it for you in the future.
Ah, that’s good to hear. So my system will come back up, it will just complain until I do these microcode changes.
So your post/comment was just being preemptive of future changes. :)
