Hi Guys, So, mkinitcpio-30 (on [testing]), uses zstd by default for initramfs images, since all our kernels now support it. I plan to move mkinitcpio in the next 24-48 hours but, since I anticipate some people holding back 5.4 kernels, I want to send the following news announcement (here [0] is the md I'm using, so feel free to help there): ---- All official kernels of Arch Linux now support zstd compressed initramfs images, so mkinitcpio is switching to zstd compressed images by default on the version that 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.
