# mkinitcpio > Generates initial ramdisk environments for booting the Linux kernel based on the specified preset(s). > More information: . - Perform a dry run (print what would be done without actually doing it): `mkinitcpio` - Generate a ramdisk environment based on the `linux` preset: `mkinitcpio --preset {{linux}}` - Generate a ramdisk environment based on the `linux-lts` preset: `mkinitcpio --preset {{linux-lts}}` - Generate ramdisk environments based on all existing presets (used to regenerate all the initramfs images after a change in `/etc/mkinitcpio.conf`): `mkinitcpio --allpresets` - Generate an initramfs image using an alternative configuration file: `mkinitcpio --config {{path/to/mkinitcpio.conf}} --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/`): `mkinitcpio --kernel {{kernel_version}} --generate {{path/to/initramfs.img}}` - List all available hooks: `mkinitcpio --listhooks` - Display help for a specific hook: `mkinitcpio --hookhelp {{hook_name}}`
