As linux-lts moved to the 5.10 version, all official kernels of Arch Linux now support zstd compressed initramfs images, so mkinitcpio is switching to zstd compressed images by default with version 30, which is currently on [testing].
If, for any reason, you are using a kernel version prior to 5.9, make sure to change mkinitcpio.conf COMPRESSION to use one of the compressors supported, like gzip, otherwise you **will not** be able to boot images generated by mkinitcpio.
I am not sure I understand this. If someone has the default mkinitcpio.conf it won't boot?
In my case I set it to lz4 over a year ago for speed.
If someone has the default mkinitcpio.conf AND a kernel older than any Arch ships, then yes, it may not boot.
