*** Boot parameters (initramfs stage)
** hooks/archiso
* archisolabel= Set the filesystem label where archiso files reside.
Default: (unset)
* archisodevice= Set the device node where archiso medium is located.
Default: "/dev/disk/by-label/${archisolabel}"
* archisobasedir= Set the base directory where all files reside.
Default: "arch"
* aitab= Set the path for "aitab" file.
Default: ${archisobasedir}/aitab
* copytoram= If set to "y" or just "copytoram" without arguments,
all SquashFS are copied to "RAM".
Default: (unset)
* cowspace_size= Set the size of tmpfs /cowspace. This space is used for
Copy-On-Write files of dm-snapshot.
(directory not visible outside initramfs)
Size is in bytes (suffix with "k", "m" and "g") or
in percentage of available RAM.
Default: "75%"
* copytoram_size= Set the size of tmpfs /cowpytoram. This space is used for
copy of all SquashFS images used, if copytoram=y.
(directory not visible outside initramfs)
Size is in bytes (suffix with "k", "m" and "g") or
in percentage of available RAM.
Default: "75%"
* arch= Force an architecture type (i686 | x86_64).
Do not set it for normal operations.
Useful for running a 64 bit kernel / 32 bit userspace.
Default: (architecture of running kernel)
** hooks/archiso_pxe_nbd
* ip= This parameter is setup automatically by PXELINUX
when option "IPAPPEND" is set to 1 or 2 in config.
ip=<client-ip>:<boot-server-ip>:<gw-ip>:<netmask>
Default: (set via PXE server)
* BOOTIF= This parameter is setup automatically by PXELINUX
when option "IPAPPEND" is set to 2 or 3 in config.
BOOTIF=<hardware-address-of-boot-interface>
Default: (set via PXELINUX)
** hooks/archiso_loop_mnt
* img_dev= Device where archiso-image.iso reside.
Default: (unset)
* img_loop= Full path where archiso-image.iso is located on ${img_dev}
Default: (unset)
*** Boot parameters (only for configs/releng)
** /etc/rc.conf
By default these parameters are set by default to these values
if nothing is specified on command line.
* locale= "en_US.UTF-8"
* daemon_locale= "no"
* hardwareclock= "UTC"
* timezone= "Canada/Pacific"
* keymap= "us"
* consolefont= (unset)
* consolemap= (unset)
* usecolor= "yes"
*** Image types generated by mkarchiso.
* image-name.sfs SquashFS image with all files directly on it.
