+*** 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)
+* checksum=         If set to "y" or just "checksum" without arguments,
+                    performs a self-test of all files inside ${install_dir},
+                    and continue booting if ok.
+                    Default: (unset)
+* cow_label=        Set the filesystem label where COW (dm-snapshot)
+                    files must be stored.
+                    Default: (unset)
+* cow_device=       Set the device node where COW (dm-snapshot) files
+                    must be stored.
+                    Default: (unset) or "/dev/disk/by-label/${cow_label}"
+* cow_directory=    Set a directory inside ${cow_device}.
+                    Default: "/persistent_${archisolabel}/${arch}"
+* cow_persistent=   Set if snapshots are persistent "P" or non-persistent "N".
+                    Default: "N" (if no ${cow_device} is used) otherwise "P".
+* cowspace_size=    Set the size of tmpfs /cowspace. This space is used for
+                    Copy-On-Write files of dm-snapshot.
+                    Size is in bytes (suffix with "k", "m" and "g") or
+                    in percentage of available RAM.
+                    Default: "75%"
+* cowfile_size=     Set the size for all files to be used as COW (dm-snapshot),
+                    in percentage of the ro-device.fs file. This is mostly useful
+                    when cow_device= is used and filesystem does not support
+                    sparse files (ie VFAT).
+                    Default: "100%"
+* copytoram_size=   Set the size of tmpfs. This space is used for
+                    copy of all SquashFS images used, if copytoram=y.
+                    Size is in bytes (suffix with "k", "m" and "g") or
+                    in percentage of available RAM.
+                    Default: "75%"
+* dm_snap_prefix=   Set a prefix for device-mapper snapshot node names.
+                    Default: "arch"
+* 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_common
+
+* 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)
+* copy_resolvconf=  Copy /etc/resolv.conf from initramfs to live-enviroment.
+                    Set to "n" to skip them.
+                    Default: "y"
+
+
+** hooks/archiso_pxe_nbd
+
+* archiso_nbd_name= Set NBD export name used by the server.
+                    Default: archiso
+* archiso_nbd_srv=  Set an IP address where NBD reside.
+                    If ${pxeserver} is used, PXE IP will be used.
+                    Default: (unset)
+
+
+** hooks/archiso_pxe_http
+
+* archiso_http_srv= Set an HTTP URL (must end with /) where ${archisobasedir}
+                    is found with all *.sfs files.

+                    Default: (unset)
+* archiso_http_spc= Set the size of tmpfs where *.sfs files are downloaded.
