*** Boot parameters (initramfs stage)

** hooks/parabolaiso

* parabolaisolabel=     Set the filesystem label where parabolaiso files reside.
                    Default: (unset)
* parabolaisodevice=    Set the device node where parabolaiso medium is located.
                    Default: "/dev/disk/by-label/${parabolaisolabel}"
* parabolaisobasedir=   Set the base directory where all files reside.
                    Default: "parabola"
* aitab=            Set the path for "aitab" file.
                    Default: ${parabolaisobasedir}/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 ${cow_device}.
                    Default: "/persistent_${parabolaisolabel}/${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: "parabola"
* 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/parabolaiso_pxe_common

                    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/parabolaiso_pxe_nbd

* parabolaiso_nbd_name= Set NBD export name used by the server.
                    Default: parabolaiso
* parabolaiso_nbd_srv=  Set an IP address where NBD reside.
                    If ${pxeserver} is used, PXE IP will be used.
                    Default: (unset)


** hooks/parabolaiso_pxe_http

* parabolaiso_http_srv= Set an HTTP URL (must end with /) where ${parabolaisobasedir}
                    is found with all *.sfs files.
                    In the IP/domain part if ${pxeserver} is used, use PXE IP.
                    Default: (unset)
* parabolaiso_http_spc= Set the size of tmpfs where *.sfs files are downloaded.
                    Default: "75%"


** hooks/parabolaiso_pxe_nfs

* parabolaiso_nfs_srv=  Set the NFS-IP:/path of the server
                    In the IP part if ${pxeserver} is used, PXE IP will be used.

* parabolaiso_nfs_opt=  Set NFS mount options separated by comma.
                    Default: (unset, see below)
                    These are the implicit options:
                      port            = as given by server portmap daemon
