Option	Description
--[no-]splash	Activates (or deactivates) support for Fbsplash framebuffer splash in the genkernel-built initrd image. To override the default theme used by fbsplash, use --splash=PreferredTheme (where PreferredTheme is the title of one of the directories inside the /etc/splash directory).
--splash-res=PreferredResolution	This option allows to select which splash screen resolutions will be supported in the initrd during the start-up of the system. This is useful for two reasons. First, to be able to select only the splash screen resolution(s) relevant to the system. Second, to avoid the unnecessary increase in the disk space required by initrd (since the initrd does not have to support resolutions that are irrelevant for the system's configuration.) However, the option is best omitted if the kernel is being compiled for an Installation CD; this allows splash support for all possible resolutions.
--do-keymap-auto	Force keymap selection during the boot sequence.
--lvm	Includes support for storage using via Logical Volume Management (LVM2) from static binaries, if available to the system. Relevant (static) LVM2 binaries are compiled if they are unavailable. Be sure to install the sys-fs/lvm2 package on the system (emerge sys-fs/lvm2) before enabling this option, then review the LVM article on the Gentoo wiki.
--dmraid	Includes support for DMRAID; the utility which creates RAID mappings using the kernel device-mapper subsystem. DMRAID discovers, activates, deactivates and displays properties of software RAID sets (ATARAID, for example) and contained DOS partitions.
--luks	Includes support for Linux Unified Key Setup or LUKS. This will allow to use a device encrypted by LUKS which contains the root filesystem. On the bootloader, set that encrypted device as the value of crypt_root (and root shall be the unencrypted device LUKS creates).
--disklabel	Adds support for disk label and UUID support to the initrd.
--iscsi	Adds support for iSCSI to the initrd.
--multipath	Adds support for Multipath to the initrd.
--linuxrc=/path/to/the/linuxrc_file	Specifies a user-created linuxrc — a script that is initialized during the start-up stage of the kernel, prior to the actual boot process. A default linuxrc script can be found in the /usr/share/genkernel/ directory. This script allows booting into a small, modularized kernel; it tries to load the minimum amount of drivers that are needed (as modules) by the system.
--cachedir=/path/to/alt/dir	Overrides the default cache location used while compiling the kernel.
--tempdir=/path/to/new/tempdir	Specifies the location of the temporary directory used by genkernel while compiling the kernel.
--unionfs	Includes support for the Unification File System in the initrd image.
--mountboot	Detects whether or not the /boot directory needs to be mounted on a separate partition. It will check /etc/fstab script for instructions on how to mount the boot partition on a file system (if needed).
