Presets are located in /etc/mkinitcpio.d +Early Init Environment +---------------------- +mkinitcpio gives special treatment to certain environment variables passed on +the kernel command line: + +*break*['=<premount|postmount>']:: + If specified, mkinitcpio will start a shell during early init. The optional + parameter controls when this occurs: when 'premount' or no parameter are + specified, the shell will be launched prior to mounting root. If 'postmount' + is specified, the shell will be launched after mounting root. + +*disablehooks=*'hooklist':: + This is a comma separated list of hooks which will be skipped during early + init. + +*earlymodules=*'modulelist':: + This is a comma separated list of modules which will be loaded prior to any + others. This is generally not needed, and usually points to a configuration + or kernel problem. + +*quiet*:: + Causes mkinitcpio to output fewer messages during boot. Errors will not be + suppressed. + +*ro*:: + Specifies that root should be mounted with readonly permissions. This is the + default behavior. + +*rw*:: + Specifies that root should be mounted with readwrite permissions. This is + generally only useful if your initramfs uses the 'fsck' hook. + +*root=*'rootdevice':: + This variable describes the root partition which early init will mount + before passing control to the real init. mkinitcpio understands a variety of + formats, the most basic of which is the path to the block device, either + directly, such as '/dev/sda2', or using a udev symlink such as + '/dev/disk/by-label/CorsairF80-root'. Support for identification by LABEL or + UUID tags are also supported, such as, 'LABEL=CorsairF80-root'. As of + util-linux 2.22, PARTUUID is also supported. Identification via hex encoded + major/minor device ID is supported for legacy reasons, but should not be used. + +*rootdelay=*'seconds':: + Sets the delay, in seconds, that mkinitcpio is willing to wait for the root + device to show up, if it is not available immediately. This defaults to 5 + seconds. If an invalid integer is passed, this variable will have no effect. + +These are only the variables that the core of mkinitcpio honor. Additional +hooks may look for other environment variables and should be documented by the +help output for the hook. + Files ----- '/etc/mkinitcpio.conf':: |
