Generate initial ramdisk environments for booting the Linux kernel based on the specified preset(s). More information: https://manned.org/mkinitcpio.8.

• Perform a dry run (print what would be done without actually doing it):

mkinitcpio

• Generate ramdisk environments based on all existing presets (used to regenerate all the initramfs images after a change in /etc/mkinitcpio.conf):

sudo mkinitcpio {{[-P|--allpresets]}}

• Generate a ramdisk environment based on the linux preset:

sudo mkinitcpio {{[-p|--preset]}} {{linux}}

• Generate a ramdisk environment based on the linux-lts preset:

sudo mkinitcpio {{[-p|--preset]}} {{linux-lts}}

• Generate an initramfs image using an alternative configuration file:

sudo mkinitcpio {{[-c|--config]}} {{path/to/mkinitcpio.conf}} {{[-g|--generate]}} {{path/to/initramfs.img}}

• Generate an initramfs image for a kernel other than the one currently running (the installed kernel releases can be found in /usr/lib/modules/):

sudo mkinitcpio {{[-k|--kernel]}} {{kernel_version}} {{[-g|--generate]}} {{path/to/initramfs.img}}

• List all available hooks:
