       fai.conf - FAI Configuration




       The configuration for a target host consists of two parts:

       ·      The  NFSROOT,  a  very  basic  yet  complete root file system, which is exported to
              clients.  The NFSROOT is built using fai-make-nfsroot(8).

       ·      The configuration space, which is loaded as one of the first steps of  a  FAI  run.
              Several  tools  and  protocols  are  supported  for  maintaining  and accessing the
              configuration space.  See FAI_CONFIG_SRC below.

       fai.conf defines the essential options to successfully start a FAI run.  It must be  valid
       bash(1) code.  This configuration file is NOT copied into the nfsroot by fai-make-nfsroot.


              This  variable  defines  how  to  access  the  configuration  space. It defines the
              protocol, the server and the location of the config space.

              For an initial installation of a client this variable  is  defined  by  using  fai-
              chboot(8).   If you do a fai softupdate, you can set the value in /etc/fai/fai.conf
              or by using the option --cspace.

       The following protocols and URL schemes are currently supported:

       ·      NFS: nfs://[server]/<exported directory>

              If the server is not specified, FAI tries to  extract  the  server  name  from  the
              nfsroot mount.

              Example: nfs://faiserver/srv/fai/config

       ·      Local directory: file://<directory>

              The  directory  has  to  be an absolute path. So, this URL always starts with three
              slashes like this: file:///

       ·      CVS: cvs[+ssh]://<user>@<host>/<cvs root> <module>[=<tag>]

              The config space is received from a cvs checkout.

       ·      Subversion: svn[+(file|http|https|ssh)]://[<user>@]<host>/<repository>

              The config space checked out from a subversion repository  using  several  protocol
              variants. Checkouts without a user name are also supported.

       ·      Git: git[+<protocol>]://<git path>

              You  can  specify the branch by adding #<branchname> without a whitspace before the

              Example: git+ssh:://user@servername/srv/git/..../fai.git#branchname

              The config space checked out from  a  git  repository,  host  can  be  empty.  Also
              supported is git+http.

       ·      Mercurial: hg+(http|https)://<hg path>

       ·      HTTP:    (http|https|scp|sftp)://<server>/<filename>    where   <filename>   is   a
              (compressed) tar archive.

              The config space will be downloaded from  the  given  location  via  the  specified
              protocol.   <filename>  will  be  extracted  by  ftar(8),  and thus needs to have a
              recognized suffix, such as .tar.gz or tar.xz.

       LOGUSER Account name on the install server to save log files and call
              fai-chboot(8).  At the end of an installation, fai(8) may connect  to  the  install
              server  using  FAI_LOGPROTO  (see  below)  to  store the generated log files and to
              change the network boot configuration of the target host.  To  fully  enable  this,
              configure .rhosts and PAM such that the configured user can log in from all install
              clients  without  password.   This  account  should  have  write  permissions   for
              /srv/tftp/fai.  For  example, you can use write permissions for the group linuxadm.
              chgrp  linuxadm  /srv/tftp/fai;chmod  g+w  /srv/tftp/fai.   If  the   variable   is
              undefined, this feature is disabled.

       FAI_LOGPROTO Protocol for saving logs
              Supported  values  are: ssh (default), rsh, ftp and none. This will only be used if
              also LOGUSER is set.

              ssh: Use the scp command to copy the log files to the log server.

              rsh: Use the rcp command to copy the log files to the log server.

              ftp: This option saves logs to the remote FTP  server  defined  by  the  $LOGSERVER
              variable  ($SERVER  value is used if not set). Connection to the FTP server is done
              as user $LOGUSER using password  $LOGPASSWD.   The  FTP  server  log  directory  is
              defined  in  $LOGREMOTEDIR.  These  variables  are also defined in file server. All
              files in the directory /tmp/fai  are  copied  to  the  FTP  server  following  this


              none: Don't save the log files to the install server.

       FAI_DEBMIRROR Access Debian mirror via NFS-mounted directory
              If  defined,  FAI  mounts the NFS share to $MNTPOINT during installation.  Example:

              The port to which FAI sents messages, if the fai-monitor  is  running.  Default  to
              4711.  See  also  fai-monitor(8).  This  variable  has to be set inside the nfsroot
              before the configuration space is available.
