NAME

       install_packages - install FAI configured packages

SYNOPSIS

       install_packages

DESCRIPTION

       This command is only called internally by FAI and not directly by the user.

       install_packages is a Perl script written for FAI to selectively install, hold, remove, or
       purge packages or tasks. Its function is to parse the package_config files  based  on  the
       class  definitions  of  the client.  For example, if the client belonged to the SMTPSERVER
       class, install_packages would parse ../package_config/SMTPSERVER for instructions on  what
       packages to install, hold, remove, or purge.

OPTIONS

       -d     Only  download  packages  instead  of installing them. Variable $aptoptions must be
              set.

       -h     Show help, version and summary of options.

       -H     Show list of all available commands for the file in package_config.

       -l     Print only the list of all packages that would be installed, then exit.

       -L     Print the list of all packages with version number that would  be  installed,  then
              exit.

       -m MAX Install only MAX packages at a time. Same as setting the shell environment variable
              MAXPACKAGES.

       -n     Dry run. Do not execute installation commands, just print them.

       -N     Do not check package names whether they are valid and remove unknown packages  from
              the list. You can also set the variable FAI_DISABLE_PACKAGE_NAME_CHECK to 1.

       -p DIRECTORY
              Read the configuration files from DIRECTORY instead of $FAI/packages_config.

       -s     Download source of binary packages that are installed. Currently supported only for
              apt-get/aptitude based installations.

       -v     Be verbose.

NOTES

       install_packages  expects  to  find  the  FAI_ROOT  directory,  the  location   of   class
       definitions,  package  configurations,  and  custom  install  scripts,  somewhere  in  the
       filesystem.
