NAME

       fai-chboot - manage the network boot configuration files

SYNOPSIS

       fai-chboot [OPTION]... KERNELNAME HOST...
       fai-chboot -l[e|d|t|o|g] [PATTERN]
       fai-chboot -e HOST...
       fai-chboot -d HOST...
       fai-chboot -c HOST|TEMPLATE HOST|TEMPLATE...
       fai-chboot -i [OPTION]... HOST...
       fai-chboot -I [OPTION]... HOST...

DESCRIPTION

       This command creates the configuration files for network booting using pxelinux and DHCP.

       KERNELNAME  is the file name of the kernel that will be booted. This kernel will mount the
       root filesystem via NFS. You can add additional kernel  parameters  and  define  some  FAI
       specific  flags.  For  each  host  one configuration file is created. The file name of the
       configuration file is its IP address in upper case hexadecimal or its MAC address with the
       prefix "01-". HOST can be a host name, an IP or a MAC address or the keyword "default".

OPTIONS

-B Set default values for FAI_FLAGS. This is the same as -f verbose,sshd,reboot

-c Copy an existing config file to one or more hosts or templates and enable them for
network booting.

-C CFDIR
Use CFDIR as the configuration directory. Default is /etc/fai. You can also set the
environment variable FAI_ETC_DIR.

-D DIR Set the directory for the network boot configuration to DIR. The default value is
/srv/tftp/fai/pxelinux.cfg/.

-d Disable the PXE configuration for the specific HOST. This renames the config file
adding the suffix .disable to it, making PXE boot fall back to the default.

-e Re-enable network booting for HOST. This renames the config file removing the
suffix .disable from it, so the next time it uses its own PXE configuration.

-E Add FAI_FLAG initial. This causes setup-storage to disable preserving partitions.
This may erase (therefore option E) data on the disk.

-f fai_flags
Set FAI_FLAGS. The flags must be comma separated.

-F Set default values for FAI_FLAGS. This is the same as -f verbose,sshd,createvt

-h Show simple help and version.

-i Set parameters for booting the FAI install kernel (proper initrd, boot from nfs).
This does not set FAI_ACTION

-I Same as -i but also sets FAI_ACTION=install. So a fully automatic installation will
be performed. ATTENTION! This will erase most of the data on the local disks of the
install clients.

-k parameters
Set kernel append parameters.

-l List the configuration for all hosts in short format. If PATTERN is given, list
only hosts matching PATTERN. Lists hostname, FAI_ACTION, kernel name and IP address
in hex. Use -le, to list only enabled hosts, -ld to list only disabled hosts, -lt
to list only templates, -lo to list only hosts that do not match any of the
previous categories, and -lg to list the configuration for all hosts, sorted and
ordered by groups (enabled, disabled, templates, others). Note that a combination
of multiple -l options is not supported and that in listing mode no other action
will be performed.

-L List the configuration for all hosts. Also list the kernel append parameters. If
PATTERN is given, list only hosts matching PATTERN.

-n Do not create configuration but show what would be done. This also enables the
verbose flag.

-o Do localboot via PXE. Do not boot via network card, but use next boot device which
is specified in the BIOS. Normally this is the local disk.

-p Preserve existing config files. The default is to overwrite an existing config
file.

-P Add the pxelinux option IPAPPEND 6 to the config file. This will add the two
variables BOOTIF and SYSUUID to the kernel command line, that are also defined as
variables inside FAI.

Example:
BOOTIF=01-08-00-27-12-34-56
SYSUUID=00234567-1111-2222-3333-123456789000

-q Query the absolute path and filename of the PXE configuration file for a host or a
list of hosts.

-s SUFFIX
Use SUFFIX to determine which kernel and initrd to use.

-S Same as -i but also sets FAI_ACTION=sysinfo.

-u URL Set FAI_CONFIG_SRC to URL. Setting this variable is mandatory for the operation of
FAI. See fai.conf(5) for the format of this variable.

-U URL Add URL to kernel and initrd file names. lpxelinux.0 can use FTP and HTTP for
getting these files.

-v Create verbose output.

EXAMPLES

fai-chboot -l
List the configuration for all hosts. fai-chboot -FSPv -u
nfs://faiserver/srv/fai/config atom02 The host atom02 will boot the FAI install
kernel but with FAI_ACTION sysinfo.

fai-chboot -l tmpl
All templates are listed.

fai-chboot -IBPv -u nfs://faiserver/srv/fai/config atom02
The host atom02 will be installed. ATTENTION! All data on the local hard disks are
lost in most cases, because we want to install a new system. After the installation
the host automatically reboots.

fai-chboot -vSP -s2.6.18-4-amd64 faiserver
Booting kernel vmlinuz-2.6.18-4-amd64
append initrd=initrd.img-2.6.18-4-amd64 ip=dhcp

faiserver has 1.2.3.4 in hex 01020304
Writing file /srv/tftp/fai/pxelinux.cfg/01020304 for faiserver

fai-chboot -IFv -u nfs://faiserver/srv/fai/clusterconf node03
node03 will be installed using the configuration space /srv/fai/clusterconf, which
is mounted from faiserver via NFS.

fai-chboot memtest86+ atom02
The host atom02 will boot the memory test. Install the package memtest86+ and copy
the executable memtest86+.bin to /srv/tftp/fai without the .bin suffix.

fai-chboot -o default
All hosts, that do not have a PXE configuration for their IP-address will do a
localboot, i.e. booting from local disk.

fai-chboot -vc lenny64 james007
This command will tell the host james007 to use the template called lenny64.
Beforehand, you have to manually create the template and save it to
/srv/tftp/fai/pxelinux.cfg/lenny64.tmpl.

fai-chboot -iFPv atom02 atom03 dom kueppers
The hosts atom02, atom03, dom and kueppers will boot the FAI install kernel.
FAI_ACTION will not be set unless specified with option -k or -I. You can also use
the script class/LAST.var on the install server to set FAI_ACTION.

NOTES Currently only PXE boot is supported.
